Q8. A box whose mass is 60 kg is on a plane inclined at 30° to the horizontal, the coefficient of friction between the box and the plane is 0.4.

Calculate EACH of the following:

(a) the time taken for the box to slide down the plane a distance of 15 m from rest under the effect of gravity. (10)

(b) the force applied parallel to the plane, to accelerate the box at 2 m/s² up the plane. (6)
