Find the speed of block and bullet immediately after impact

Reference no: EM13666479

A 12 gram bullet is fired into a 100 gram wooden block initially at rest on a horizontal surface. After impact, the block slides 7.5 meter before coming to rest. The coefficient of kinetic friction between the surface and the block is 0.65.

a. Find the speed of the block and bullet immediately after impact?

b. Determine what was the initial speed of the bullet?
