Q. A 10.0 g bullet is fired horizontally into a 100 g wooden block that is at first at rest on a frictionless horizontal surface and connected to a spring of constant 158 N/m. The bullet becomes embedded in the block. If bullet-block system compresses the spring by a highest of 88.0 cm, what was the speed of the bullet at impact with the block?
