The metal ball has a mass of 2.1g. It falls a distance of 0.80m between being released and reaching the bottom of the tube. (1) Calculate the gravitational potential energy transferred from the ball as it falls. gravitational potential energy transferred = [2] (ii) When the ball reaches the bottom of the tube, it has a speed of 1.2m/s. Calculate the kinetic energy of the ball at the bottom of the tube. kinetic energy = [3]
