Simple Harmonic Motion (SHM)

Questions 1821 refer to the following information of simple harmonic motion:

A 1.95-kg block is hung by a vertical spring with k = 80 N/m. A 0.05-kg bullet is fired vertically at the block and is stuck inside the block. The speed of the bullet just before the impact is 200 m/s.

 

18. By using the conservation of momentum, find the speed of the block after the impact.

a) 4.7 m/s

b) 5 m/s

c) 6 m/s

d) 8 m/s

e) 10 m/s
