A box slides down a plane 8m long that is inclined at an angle of 30 degrees with the horizontal. If the box starts from rest and µ= 0.25, find a) the acceleration of the box b) its velocity at the bottom of the plane and c) the time required for it to reach the bottom. If the box in the previous problem has a mass of 60kg, how much force is needed to move it up the plane a) at a constant velocity and b) with an acceleration of 2m/s2. There was no diagram for the previous problem.
