The position vector of two particles of mass 4.0 kg and 2.0 kg are, respectively, r⃗1 = 2t^2î + tĵ + 3k̂ and r⃗2 = 4tî – ĵ + 3t^2k̂ where t is in seconds and the position in metres. Determine the position vector of the centre of mass of the system, the velocity of the cm and the net force acting on the system.

A bullet of mass 20 g, travelling at a speed of 350 ms^-1, strikes a steel plate at an angle of 30º with the plane of the plate. It ricochets off at the same angle, at a speed of 320 ms^-1. What is the magnitude of the impulse that the steel plate gives to the bullet? If the collision with the plate takes place over a time Δt = 10^-3 s, what is the average force exerted by the plate on the bullet?
