Q. An 11.0 g bullet is fired horizontally into a 108-g wooden block that is at first at rest on a frictionless horizontal surface and connected to a spring of constant 151 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a highest of 90cm, what was the speed of the bullet at impact with the block?
