Problem
A block rests on a smooth plane inclined at an angle θ to the horizontal. Answer the following questions.
(a) Part 1: (i) Draw a neat free-body diagram of the block and label all forces acting on it.
(b) Part 2: (ii) Explain, without carrying out any numerical calculation, why the acceleration of the block down the plane is independent of its mass.
(c) Part 3: (iii) Describe how the normal reaction acting on the block varies with (a) the mass of the block and (b) the angle of inclination θ.
