Having missed most of this material, I am finding myself at odds wih the last question of a homework assignment:
A bullet of mass 4.0 g moving horizontally with a velocity of 500 m/s strikes a wooden block, initially at rest, on a rough wooden surface. The bullet passes through the block in a negligible time interval, emerging with a velocity of 100 m/s and causing the block to slide 40 cm along the surface before coming to rest. With what velocity does the block move just after the bullet exits?
Can anybody suggest a good way to set up this problem?
