A catapult fires a stone with a speed of u = 7.0 m s¹ from a vertical height of 1.0 m above level ground, as shown in Figure 2. A student tests the device by aiming the stone so that, at its highest point, it just clears a barrier with a height of 3.0 m. The stone then lands in the middle of a frozen pond, whose surface can be assumed to be at the same level as the ground.
