A(n) 8.9g bullet is fired into a(n) 132g block
of wood at rest on a horizontal surface and
stays inside. After impact, the block slides
13m before coming to rest.
The acceleration of gravity is 9.8 m/s^2/
If the coeffcient of friction between the
surface and the block is 0.5, find the speed of
the bullet before impact. Answer in units of
For this problem, the only direction I know where to go in is to solve for the force of friction. Because we have the coefficient of friction and the normal force (9.8 * .132kg) the friction force = .6468N. So now where do I go with this?
