Ali is whirling a 2.0 kg bunch of bananas in a circular path having a radius of 0.50 m. The bananas complete 2 revolutions every 6.0 seconds.
1. What force must he apply to keep the motion constant so that the bananas complete one revolution every 4 seconds?
2. A coin is on a turntable that rotates pi rad/s. The coefficient of static friction between the coin and the turntable is 0.25.
A. Calculation the maximum distance of the coin from the center of the turntable for it to move in a circle.
B. If the coin is placed at a distance of 4.7cm from the center of the turntable, what is the maximum speed of rotation of the turntable for the coin to move relative to the turntable without slipping?
