A. Acceleration is the answer to you question. When an object changes velocity it can accelerate.<span />
Answer:
The bending moment is 459.16 N.m
Explanation:
From the given information;
Let's assume that the angle is 66°
Then, the free body diagram is draw and attached in the file below.
Now, the calculation of the acceleration from the first part of the free body diagram is:

Bending moment M:
From the second part of the diagram:

The answer is "the product of the object's moment of inertia and the object's angular velocity.
A. At the top. At this point, the child is highest, and they are not moving. Their potential energy is much greater.
