The block shown in Figure has mass m = 7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ= 22.0o to the horizontal.
(a) Determine the acceleration of the block as it slides down the plane.
(b) if the block starts from rest 12.0 in up the plane from its base, what will be the block's speed when it reaches the bottom of the incline?
