A(n) 9.9 g bullet is fired into a(n) 138 g block of wood at rest on a horizontal surface and stays inside. after impact, the block slides 13 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 0.6, find the speed of the bullet before impact. answer in units of m/s.
