Emma drops a rock from the top of a cliff. The rock has a mass of 0.5 kg. As the rock falls it loses potential energy and gains kinetic energy. The rock is travelling at a speed of 15 m/s just before it hits the ground. Calculate the distance the rock falls. Take the value of g to be 10 N/kg. Ignore the effect of air resistance.
