## Problem 10.2: Determine angular and tangential speed and velocity

Please wait for the animation to completely load.

A child sits on a merry-go-round at the position marked by the red circle **(position is given in meters and time is given in seconds)**. Restart.

- What is her average speed and instantaneous velocity?
- What is her angular speed and angular velocity?

For the instantaneous velocity and angular velocity, you should give a value for the speed and a description of the velocity's direction for any point in time.
