A1.0 kg toy car is released at the top of a frictionless track on the left and rolls off of the track from its right side ramp. The car starts at a height of 0.80 m, goes through a 0.50 m diameter loop, and exits the
- ramp at a height of 0.25 m.

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?
