Two students each throw a ball horizontally from the top of a tower. The two balls are released at the same time. The first student throws her ball with a speed of 20 m s–1 and the second student throws his ball with a speed of 10 m s–1. Assume air resistance is negligible and that the balls land on horizontal ground. Which row describes the horizontal distances travelled and the landing times of the two balls on the ground?
