Me and my friend are playing on a Ferris wheel which has Radius of 20 Meter and had an constant angular velocity of 0.2 rad/s .
Then, When I'm at the very top of the Ferris wheel i'm going to drop a tennis ball( dropping without initial velocity).
How far around the Ferris wheel in radian from me should my friend sit,
so he can catch the ball?
The acceleration of gravity is −9.8 m/s^2.
air resistance is neglected.
