The final speed of the car and minivan is 17.95 m/s

The mass of the car = 950 kg

The speed of the car = 22 m/s

The mass of the minivan = 1300 kg

The speed of the minivan = 15 m/s

The final speed of the car and minivan can be found using the conservation of momentum formula,

                 [tex]\displaystyle m_{1}v_{i1 } + m_{2}v_{i2} = m_{1}v_{f1} + m_{2}v_{f2}[/tex]

where [tex]\dispplaystyle m_{1}[/tex] is the mass of the car

           [tex]\dispplaystyle m_{2}[/tex] is the mass of the minivan

           [tex]\dispplaystyle v_{i1}[/tex] and [tex]\dispplaystyle v_{i2}[/tex] is the initial speed of the car and minivan respectively.

          [tex]\dispplaystyle v_{f1}[/tex] and [tex]\dispplaystyle v_{f2}[/tex] is the final speed of the car and minivan respectively.

As the two cars move together, they would have the same final speed, i.e.

                    [tex]\dispplaystyle v_{f1} = \dispplaystyle v_{f2} = \dispplaystyle v_{f}[/tex]

Thus, the above equation becomes,

                      [tex]\displaystyle m_{1}v_{i1 } + m_{2}v_{i2} = (m_{1} + m_{2})v_{f}[/tex]

Let us substitute the known values in the above equation, we get

                       (950 x 22) + (1300 x 15) = (950 + 1300) [tex]\displaystyle v_{f}[/tex]

                                  20,900 + 19.500 = 2,250 [tex]\displaystyle v_{f}[/tex]

                                                  40,400 = 2,250[tex]\displaystyle v_{f}[/tex]

                                     40,400 / 2,250 = [tex]\displaystyle v_{f}[/tex]

                                                               = 17.95 m/s

Therefore, the final speed is 17.95 m/s

The speed of the sled after it has travelled a distance 3.58 meter is 2.96m/s.

Mass of sled = 2.49kg

Initial speed across the horizontal surface = 4.53m/s

Coefficient of kinetic friction between the slate and surface = 0.168

Distance = 3.58m

Now to calculate the acceleration of sled we use :

F = ma

a = F/m

where

a = acceleration

m = mass

F = frictional force

a = μmg / m

a = μg

a = 0.168 x 9.8

The forces applied on the bucket are tension and gravitational.

What is the gravitational force?

According to Newton’s gravitational law, it is the force exerted due to attraction between two objects that is directly proportional to the product of their masses and is inversely proportional to the square of distance between them.

The force applied to the bucket containing water is gravitational force. The gravitational force acts in downward direction and there is no change in the state of motion. There is another force as well which is the muscular force by which we hold the bucket in the upward direction with the help of our muscles. Tension is also exerted on the bucket as this force is seen in existence when any object is being pulled up with the help of string or rope. It is always seen in the direction which is parallel to the rope.

The length of the beam on which the the two boys are lying is 1.01 m.

The mass of one kid is 30 kg and the mass of the beam is 20kg, the beam is balanced at a distance of 1.10 m from the 30 kg boy when a 40kg boy was sitting at the other end of the beam.

If the beam is balanced at 1.10 m from the 30kg boy it means that there lies the center of mass of the system.

So, let us assume the length of the beam to be X meters and the assume the center of mass to be at center.

So,

0 = M₁X₁ + M₂X₂/M₁+M₂

M₁ is 30kg and X₁ is 1.10m.

M₂ is 40kg and the X₂ is (X-1.10)m.

The speed of the child and sled at the bottom of the slope is 11 m/s.

Mechanical energy, is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that mechanical energy is constant if an isolated system is subjected to only conservative forces.

Combined mass (m) = 40 kg

Speed at top of slope (v) = 5 m/s

Height of slope (h) = 10 m

Entire range of the slope (d) = 100 m

Force of friction (F) = -20 N

Work done by friction (W) = F × d

= -20 × 100

= -2000 J

Kinetic energy (KE) of sled at the top of slope = ¹/₂ mv²

= ¹/₂ × 40 × 5²

= 500 J

Potential energy (PE) of sled at the top of slope = mgh

= 40 × 9.8 × 10

Now, total energy (E) of sled/child system at the top of slope = KE + PE

= 500 + 3920

= 4420 J

So, the energy left at the bottom of slope:

4420 J - 2000 J

Saturn radiates even more excess energy than Jupiter Helium rain gives off heat as it differentiates toward Saturn's center. Option B.

Its density is so low that it floats on water. Like Jupiter, Saturn emits almost twice as much energy as it receives from the Sun. This is because it has its own internal heat source driven by the slow gravitational collapse that began with the planet's formation. The Jupiter planet draws heat from the Sun and from within.

Jupiter produces a lot of internal heat and emits thermal radiation to release this heat. In fact, Jupiter produces so much internal heat that it emits almost twice as much energy as it receives from the Sun. Hydrogen exists in a liquid metallic state around the central rocky core and surrounds the inner half of the planet.

v² = u² + 2 a s

v² = 1 + ( 2 * 9.8 * 10 )

v² = 197 m / s

v = 14 m / s

When the velocity vector is less than its maximum scale, the tip of the vector serves as the origin of the acceleration cue (6 KTGS). When the velocity vector is at or above maximum scale, the center of the LOS reticle serves as the origin of the acceleration cue.

Knowing that the system is in equilibrium at y=0, or when displacement and acceleration are both equal to zero, is known as the velocity maxima. As a result, the maximum velocity in simple harmonic motion at a given place can be calculated using the formula v=A. A velocity vector shows the rate of change in an object's position. The magnitude of a velocity vector represents an object's speed, whereas the vector's direction represents an object's direction. The apex—the highest point on any trajectory—is reached when vy=0.

a) Mass of displaced water is 41.4 g or 0.0414 kg

c) Average density of the bone is 1.09 g/ mL or 0.00109 × 10⁻⁶ Kg /m³

In the given question we have, the weight of some bird bones is measured in air outside of some water and the weight is 45.0 grams and the apparent weight in water is 3.60 grams. Now, we shall find out the weight of the displaced water? So the buoyant force is this difference between the weight of the bones out of the water and in the water, so the weight out of the water times g minus the weight in the water times g and then the g can be factored in and the buoyant force is also equal to the weight of the displaced fluid from Archimedes' principle

i.e., 45 × g - 3.60× g = weight/ mass of displaced water

weight of displaced water = 41.4 × g

g× mass of displaced water = 41.4 ×g

=> mass of displaced water = 41.2 grams

a) Mass of displaced water = 0.0414 Kg

b) the volume of the bones is going to be equal to the volume of water displaced.

We know that the density of water is the mass of water displaced divided by the volume of water. So the volume of water displaced is the weight of the water displaced divided by the density of the water.

Volume of water displaced = 41.4 grams / density of displaced water

density of water displaced = 1 grams / milliliters

So, the density of water is 41.4 milliliters or 41.4 ×10⁻⁶ m³

c) The average density of the bone is the weight of the bone divided by its volume,

Average density of bone = 45 grams / 41.4 mililitres
