An asteroid with a mass of 75 kg is travelling in deep space, far away from the the gravitational pull of any large body. It is moving at a speed of uA = 5.0 ms-1, in the positive x direction towards another smaller asteroid B which has a mass of 65 kg - which is stationary. Following the collision the asteroids move at 54° to each other and both at 27° to the original direction with speeds vA and vB. If neither asteroid is spinning prior to or following the collision, show that the collision is inelastic.
