A(n) 14 g bullet is fired into a(n) 121 g block of wood at rest on a horizontal surface and stays inside. After impact, the block slides 8.3 m before coming to rest. The acceleration of gravity is 9.8 m/s 2 . If the coefficient of friction between the surface and the block is 0.7, find the speed of the bullet before impact. Answer in units of m/s
