1. John Doe gets to go to the race track for a day. The track he is driving on is a perfect circle 750m in radius. If he is driving at 30m/s around the track, what is the centripetal acceleration experienced by the car, and what is the rotational velocity of the car?
2. Josh Beckett starts throwing his pitch; we assume that his arm moves in a perfect circular arc, and his arm is 0.7 m long. If he needs to release the ball with a tangential velocity of 35m/s what centripetal acceleration is required to achieve this?
