A small coin is placed on a flat, horizontal turntable. The turntable rotates at a constant rate of 45 rpm: It is observed to make 3 rotations in 4.0 s. When viewed from above, the turntable rotates counterclockwise. (a) A coin rides without slipping at a distance of 5.0 cm from the center of the turntable. What is the speed of the coin? (b) What is the acceleration (magnitude and direction) of the coin in part (a)? (c) Draw a free-body diagram of the coin. Label all of the forces in your diagram.
