A ball on a string moves in uniform circular motion. You need to find the centripetal acceleration, force, and the period of revolution.
Formula Sheet
a_c = v²/rF_c = mv²/rω = v/rT = 2πr/vWhat is the centripetal acceleration of the ball? (v = 3 m/s, r = 1.2 m)
What centripetal force must the string provide? (m = 0.5 kg)
What is the period T of the circular motion?
Which direction does centripetal acceleration point?
