*A 50 g ball of clay traveling at speed v_i hits and sticks to a 1.0 kg block sitting at rest on a frictionless surface.(adsbygoogle = window.adsbygoogle || []).push({});

1.What is the speed of the block after the collision?

2. What percentage of the ball's initial energy is "lost"?

*A vertical spring with k = 490 N/m is standing on the ground. You are holding a 5.0 kg block just above the spring, not quite touching it.

1.How far does the spring compress if you let go of the block suddenly?

2.How far does the spring compress if you slowly lower the block to the point where you can remove your hand without disturbing it?

i would appreciate if u would help me with these problems or try to guide me at least ^^
