A stone having a mass of 0.100 kg rests on the frictionless, horizontal surface. A bullet of mass 2.50 g traveling horizontally at 500m/s hits the stone and rebounds horizontally at right angles to the original direction with a speed of 300m/s.
i) Calculate the magnitude of velocity of the stone after it is struck.
ii) Calculate the direction of the velocity of the stone after it is struck. (Degrees from initial direction of the bullet)
