You put a ball on the end of a string. you swing the ball
with a rotation speed of 5.6 m/s. the mass of the ball is
2.0 kg. the length of the string is 1.60 m. calculate the
centripetal acceleration.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
