5 marks Long answer
In the given arrangement of a doubly inclined plane two blocks of masses M and m are placed. The blocks are connected by a light string passing over an ideal pulley as shown. The coefficient of friction between the surface of the plane and the blocks is 0.25. The value of m, for which M = 10 kg will move down with an acceleration of 2 m/s²?

A particle moves from the point (2.0î + 4.0ĵ)m, at t = 0 with an initial velocity (5.0î + 4.0ĵ)ms⁻¹. It is acted upon by a constant force which produces a constant acceleration (4.0î + 4.0ĵ)ms⁻². What is the distance of the particle from the origin at time 2s?
