A 100-g bullet is fired horizontally into a 14.9-kg block of wood resting on a horizontal frictionless surface, and the bullet becomes embedded in the block. If the muzzle speed of the bullet is 250. m/s, a) what is the speed of the block immediately after the impact? b) what is the average force acting on the block during that 8.50 ms collision?
