Ablock of mass m=16.8 kg is sliding on a surface with initial velocity v=23.2 m/s. the block has a coefficient of kinetic friction μk =0.426 with respect to the surface and is being pushed by a force of magnitude f=86.4 n in the direction of its motion. due to kinetic friction, the block is slowing down. how long will it take for the block to come to a stop?

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?
