Question

A springboard diver starts a dive with a forward rotation in which her body and arms are extended in a straight line. We can model her as a uniform rod. She then does a tuck in which she touches her fingers to her toes, folding her body+arms length in half. The ration of her new angular speed to her old angular speed is i.
1/2
ii. 1 iii. 2 iv. 4 v. 8

Answer 1

The definition of angular speed is the rate at which angular displacement changes, and it is written as follows: = t. The angular displacement is denoted by the time by t, and.

What is angular velocity and speed?

The angular velocity (w), a vector quantity for uniform circular motion, is determined by dividing the angular displacement (), also a vector quantity, by the change in time (t). Speed is equal to |w|R and is calculated by dividing the arc length traveled (S) by the change in time (t).

Is the speed of an object angular?

At every point along the circular path, the angular speed is constant, but the linear speed is not. It does so because at every point along the uniform circular path, the moving body moves at the same angle and at the same speed.
