A 3.00 kg block starts from rest at the top of a 36.0'> incline and slides 2.00 m down the incline in 1.60 s.
(a) Find the acceleration of the block.
(b) Find the coefficient of kinetic friction between the block and the incline.
(c) Find the frictional force acting on the block.
(d) Find the speed of the block after it has slid 2.00 m.
average velocity= distance/time
B) you know final velocity(2*avg velocity)
Hmmm. I don't see how it can be done without slope.
