A 5.00 g bullet moving with an initial speed of v0 = 405 m/s is fired into and passes through a 1.00 kg block, as in Figure P13.58. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with a spring constant of 950 N/m.

(a) If the block moves 5.00 cm to the right after impact, find the speed at which the bullet emerges from the block.
m/s
(b) If the block moves 5.00 cm to the right after impact, find the mechanical energy lost in the collision. J
I don't know where to begin, its so frustrating
