A 0.19 kg mass is held at rest against a compressed spring with a spring constant...

A 0.19 kg mass is held at rest against a compressed spring with a spring constant of 103 N/m. When released, the mass leaves the spring with a speed of 6.28 m/s. Assuming that the spring force if wholly responsible for changing the motion of the mass, by what distance was the spring initially compressed from its equilibrium position?

    Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m...
