a 10kg block is allowed to slide down a ramp with Mk=0.15. what is the acceleration of the block?

slope of ramp?  Damon, Wednesday, March 17, 2010 at 4:57pm
I do not know what Mk is
Need slope of ramp and friction coefficient.

By the way, the mass should not matter.

The numerical value of acceleration, a, will depend upon the angle of the block. Call that angle "A".
Acclerating force = M g sin A
Friction force = M g cos * Mk
Mg(sin A  Mk cos A) = M a
a = g(sinA  Mk*cosA)
