Explanation:

The moment of A about B is given by the formula

[tex]M=Fd[/tex]

where M is the moment, F is the force acting perpandicular to the axis of rotation about B by A, and d is the horizontal distance of A from B along the axis of rotation.

Now

[tex]F=230 (N)[/tex]

(a) At X,

[tex]M=(230)(4/2)=460 (Nm)[/tex]

(b) At 0.5m from X,

[tex]M=(230)(2-0.5)=345 (Nm)[/tex]

(c) At Y,

[tex]M=-(230)(2)=-460 (Nm)[/tex]

where negative sign indicates clockwise rotation of the child about Z.

(d) At Z,

[tex]M=(230)(0)=0 (Nm)[/tex]

Answer:

One must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Explanation:

• The distance of an object can be defined as the complete path travelled by an object.

• To find the distance, find its north component.

• For reference see the below graph:

[tex]$$\[\begin{align}& D_{south} = 80\sin \left( {58 \cdot {5^ \circ }} \right) \\& D_{north} = 80\cos \left( {58 \cdot {5^ \circ }} \right) \\\end{align}\]$$Since, $\sin \left( {58 \cdot {5^ \circ }} \right) = \cdot 853$ and $\cos \left( {58 \cdot {5^ \circ }} \right) = \cdot 5224$: therefore,$$\[\begin{align} D_{south} &= 80 \times \left( { \cdot {{853}^ \circ }} \right) \\ \Rightarrow {D_{south}} &= 68 \cdot 24\,miles \\ \end{align}\]$$[/tex]

And

[tex]$$\[\begin{align} D_{north}& = 80 \times \cdot 5224 \\ \Rightarrow D_{north}& = 41 \cdot 8\,miles \\ \end{align}\]$$[/tex]

• Hence, one must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Answer:

The most common of these is carbon 12, 13, 14. All of these isotopes have the same atomic number but different mass numbers. Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers.

Certainly a coaster could be designed without considering any one item of mass, gravity, or rates of direction change, but the success of the ride would be highly suspect.

Ignoring mass (of cars and/or riders) could lead to support members not being strong enough.

Ignoring rates of change of direction could lead to support members not being strong enough or make the forces on the riders uncomfortable.

Ignoring gravity could lead to support members not being strong enough or make the forces on the riders uncomfortable.

Third class lever

Explanation:

Suppose the cheetah is initially positioned at x=0 (m) from the reference, and the gazelle is intially at poisiton x=d (m).

Then, at the worst case, that is when cheetah is running at the maximum case, the position of the gazelle relative to the reference must be larger than that of cheetah.

In equation form,

[tex]0\text{ km}+\frac{100\text{ km}}{1 \text{ hr}}\cdot30\text{ s }\cdot\frac{1\text{ hr}}{3600\text{ s}}\le d \text{ km}+\frac{80\text{ km}}{1 \text{ hr}}\cdot30\text{ s }\cdot\frac{1\text{ hr}}{3600\text{ s}}[/tex]

[tex](100-80)\cdot \frac{30}{3600}\le d[/tex]

[tex]d\ge \frac16\text{ km}=166.66 \text{m}[/tex]

The minimum distance that a gazelle running 80.0 km/hr be ahead of the cheetah to escape is 6.5807km

If a cheetah can maintain its maximum speed of 100 km/hr for 30.0 seconds, the distance covered by the cheetah is expressed as:

Distance  = Speed * time

Given the following:

Distance covered = 100 * 0.00833333

Distance covered = 0.0833 km

If gazelle is running at a speed of 80.0km/hr, the distance of gazelle will be expressed as:

Taking the difference in distance = 6.6664km - 0.0833 km =6.5807km

Hence the minimum distance that a gazelle running 80.0 km/hr be ahead of the cheetah to escape is 6.5807km

Explanation:

The motion of an object can be described by its speed, position, and direction so its all of the above

Answer:

C

Explanation:

Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.

Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)

The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,

The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.

Thus, the correct answer is option C.

Answer:

the speed after 2 seconds = 20m/s

Explanation:

I took g as -10m/s² because the ball was moving against gravity

using V = u + gt

V = 40 - 10 X 2

V = 40 - 20

V = 20m/s

The velocity after 2 seconds later will be 20.38 m/s.

Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.

Average velocity can be given as;

Average velocity = total distance / total time taken

Velocity has a huge amount of application in science and technology.

Units of velocity are given by ⇒ meter/second

The kinetic energy of an object is caused due to velocity only.

For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.

Given that,

Initial velocity u = 40 m/s

Time period t = 2 seconds

By newtons first equation of motion

v = u - gt ( since acceleration is upward)

v = 40 - 9.81 × 2

v = 40 - 19.62

v = 20.38 m/s

Hence "The velocity after 2 seconds later will be 20.38 m/s".
