Question

A bullet m = 0.001 kg moves with a speed of 500 m/s and strikes a block M = 2 kg at rest.After the collision the bullet becomes embedded into the block. The block is attached to the end of a spring k = 120 N/m.

a. What is the initial kinetic energy of the bullet?

b. What is the speed of the bullet-block system after the collision?

c. What is the kinetic energy of the bullet-block system after the collision?

d. What is the maximum elastic potential energy when the block comes to rest?

e. What is the maximum compression of the spring?

f. What is the period of oscillations?

Answer 1

Answer:

just apply conservation of energy formula you will find it very easily then not a tough question. it is question from MTG book.

have a nice day
