Homework Help: Physics

Posted by Angela on Friday, May 15, 2009 at 12:02pm.

A force of 40 N is applied at an angle of 30oabove the horizon to a 5 kg block that is at rest on a rough horizontal surface. After the block starts to move with an acceleration of 3 m/s2, what is the coefficient of kinetic friction between the block and the horizontal surface?

How do I solve a friction problem without knowing the coefficient and vice versa?
