Trying to figure this problem...
A bullet moves with a speed 5560 cm/s, strikes an 8.45 kg block resting on the table, and bounces straight back with a speed of 1260 cm/s. Find the speed of the block immediately after collision.
P before = P after
I'm unsure of how to solve without knowing the mass of the bullet.
