A little girl is playing with her foot jump. The ball in her foot jump is in a uniform circular motion and makes 20 revolutions in 4 seconds. What is its period? What is its frequency? If the length of the plastic cord that holds the ball is 0.87 m, then what is the speed of the ball? If the ball has a mass of 4g, then how much force is acting on the ball to keep it in uniform circular motion?
