Question

A block of wood of mass 1.0 kg is initially at rest on a frictionless horizontal surface as shown in the figure. A bullet of mass 50 g traveling at 100 m/s strikes the block and becomes embedded in it. The block-bullet system slides along the surface and up a frictionless incline. What is the maximum height above the surface (in m) the block-bullet system reaches before sliding back down the incline?

Explanation / Answer

Initial Momentum = 0.05 x 100 = 5

Final momentum = (1+0.05) x v

by conservation pf momentum

5 = 1.05 v

so , v = 4.76 m/sec

Height risen = v2 / 2g = 1.156 m

Therefore, the answer is 1.156 m
