A(n) 11 g bullet is ﬁred into a(n) 111 g block

of wood at rest on a horizontal surface and

stays inside. After impact, the block slides

14 m before coming to rest.

The acceleration of gravity is 9.8 m/s

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
