Q1. A .800 kg block is attached to a spring with spring constant 16.0 N/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 41.0 cm/s. What is the amplitude of the subsequent oscillations? The block's speed at the point where x= 0.50 A?
Q2. A 33.2 m steel wire and a 25.6 m copper wire both with 1.00 mm diameters, are connected end to end and are stretched to a tension of 120 N. How long does it take the transverse wave to travel the entire length of the two wires?

A 65Kg ice skater pushes off his partner and accelerates backwards at 1.3m/s^2. If the partner accelerates in the opposite direction at 2.0m/s^2, what is mass of the other skater.
If the mass of both weights is 150 gm, the first mass is located 30 north of east, the second mass is located 30 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Suppose the transducer h..
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
