A 16.0-g bullet is shot into a wooden block at rest with mass 4550 g on a frictionless surface. The bullet strikes and is lodged in the block, causing is to slide at a speed of 1.20 m/s. Find the speed of the bullet (in m/s) before striking the block.

Answer 1

conservation of momentum applies

.016*V=(.016+4.550)*1.2
solve for V
