a cannonball is fired with a velocity of 551 m/s in the cannon is aimed 12° above the ground , how far away does the cannonball land?

Answers

The cannonball lands 12.4 km from the cannon if the cannonball is fired with a velocity of 551 m/s in the cannon is aimed 12° above the ground.

R = u² sin 2θ / g

R = Horizontal range

u = Initial velocity

θ = Angle made with ground

g = Acceleration due to gravity

u = 551 m / s

θ = 12°

g = 9.8 m / s²

R = 551² sin 2 ( 12° ) / 9.8

R = 303601 * 0.4 / 9.8

R = 12392 m

R = 12.4 km

The horizontal range of a projectile is the horizontal distance travelled by the projectile from the point from which it was launched. It is denoted by R.

A crate is pushed off the edge of a building which is 160 m tall. The crate lands 35 m from the base of the building.
a) how fast was the crate pushed?
b) how fast will it be moving when it hits the ground?

Answers

By considering the horizontal component of the motion, the speed at which the crate was pushed is 13.1 m/s. Also, by considering the vertical component of the motion, the speed at which it hits the ground is 56 m/s

Motion Under Gravity

Motion of any object under gravity is the vertical motion of the object moving under the influence of acceleration due to gravity.

Given that a crate is pushed off the edge of a building which is 160 m tall. The crate lands 35 m from the base of the building.

a) how fast was the crate pushed can be known with the use of the formula R = ut

Where

R = 35 mu = the speed at which the create is pushedt = ?

From the vertical perspective, h = ut + 1/2gt²

where u = 0 and h = 35 m

35 = 1/2 × 9.8 × t²

35 = 4.9t²

t² = 35/4.9

t² = 7.14

t = √7.14

t = 2.67 s

Substitute t and R into the formula R = ut to get u

35 = 2.67u

u = 35/2.67

u = 13.1 m/s

b) how fast will it be moving when it hits the ground can be known by using the formula

v² = u² + 2gH

v² = 0 + 2 × 9.8 × 160

v² = 3136

v = √3136

v = 56 m/s

Therefore, the crate was pushed as fast as 13.1 m/s and it was moving as fast as 56 m/s when it hits the ground.

what are the forces acting on the rock that is sliding at a constant speed on a frictionless surface? (ignore air resistance unless otherwise stated)

Answers

The forces acting on the rock that is sliding at a constant speed on a frictionless surface are the normal force and weight force of the rock itself (ignoring the air resistance).

Normal force is the force exerted by surfaces to prevent solid objects from passing through them. Normal force is also known as contact force. Meanwhile, weight force is a constant force acting on all objects on the Earth because gravitational force pulls them downward toward the Earth's center.When an object (in this case, a rock) is at a constant speed on a frictionless surface, its net force in y-axis is equal to zero. Thus, the downward force (weight force) must equal the upward force (normal force).

Because of the earth's large mass and solid structure, the skier moves but the earth does not.

Why can't the earth be moved?Because the Earth is such a massive body, it cannot be moved by applying force to it. Because it cannot be moved with a small amount of forceThe amount of matter contained in an object is what gives it inertia, or the tendency of matter to remain at rest if at rest, or to continue moving in the same direction at the same speed if moving. The greater an object's mass, the greater its gravitational force.Mass is the quantity that is solely determined by an object's inertia. The greater an object's inertia, the greater its mass. A heavier object is more likely to resist changes in its state of motion. we can conclude that the skier moves but the earth does not due to the large mass of the earth and its solid structure.

i need help with converting kinetic energy into potential

Answers

All electrons have energy stored in them which is potential energy.

Pressure increases the electron's kinetic energy causing it to move faster and eventually jump to a wider orbit. Each electron then stores energy, which becomes potential energy. Kinetic energy can be converted into other forms of energy and vice versa. For example, kinetic energy is converted into electrical energy by a generator or into thermal energy by a car's brakes.

Energy is not destroyed or lost in the transition from potential energy to kinetic energy. It just converts from one type of energy to another type of energy. This is known as the law of conservation of energy. When a person rides a bicycle to the top of a hill, the kinetic energy of movement is converted into potential energy and stored in the bicycle at the top of the hill. The potential energy stored in the bike at the top of the hill can be used to roll the bike down the hill.

How have glider pilots learned to use convection currents to stay in the sky and travel long distances?.

Answers

The air at ground level rises to form convection currents.

It creates lift upon collision with the glider's wing allowing it to stay in the air or even rise to higher altitudes. Thermals occur when the sun heats the ground and the ground warms the air above. As small plumes of warm air rise, they gather together to form thermals, the perfect place for gliders to fly and stay airborne. So the density of nearby air decreases.

This less dense air rises and helps birds fly farther. Dense air replaces this space. This movement is known as convective air currents. We know that draft is the movement of air uplifted by temperature differences between rising strata. Therefore, when a bird flies over this updraft column, this convective air current allows the bird to reach higher altitudes without additional effort.

Answers

If two wind-driven waves moving from different directions came together in such a way that the wave crests overlap to form a single crest, it would become larger than that of the two original waves.

v = 9.8 m/s.

The torso's deceleration over the specified distance is

v² = u²+2as

a = v²-u²/2s

a = 0-  9.8²/2*0.7

a = 68.6m/s²

The average amount of force his legs apply to his body as he slows down is:

F = ma

F = 50× 68.6

F = 3430 N.
