A 10.9 g bullet is fired horizontally into a 69 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a massless spring of constant 181 N/m. The bullet becomes embedded in the block. The acceleration of gravity is 9.8 m/s2 . If the bullet-block system compresses the spring by a maximum of 89.2 cm, what was the speed of the bullet at impact with the block?
