Abowling ball has an initial momentum of +30 kg m/s and hits a stationary bowling pin. after the collision, the bowling ball leaves with a momentum of +13 kg • m/s. what is the magnitude of the final momentum of the bowling pin if it has a mass of 1.5 kg? 0 kg • m/s 11 kg • m/s 17 kg • m/s 43 kg • m/s

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?
