Question

Item at position 1John decides to head to the park to experience the physics he teaches. He notices the merry go round is an excellent example of rotational motion. If he takes 3.61 seconds to go around the merry go round once, what is his angular displacement (in radians!) during 1 second?

Answer 1

First, calculate the angular speed of John, as follow:

Now, to determine the angular displacement in 1 second, Take into account that if the angular speed is 1.74 rad/s.

It means that in 1 second, John has an angular displacement of 1.74 radians.
