Two 64 kg stick figures are performing an extreme blob jump as shown in the diagram to the right
One stick figure stands atop a 7.0 m high platform with a 256 kg boulder. A second stick figure stands a partially inflated airbag known as a blob (or water trampoline). The first stick figure rolls the boulder off the edge of the platform. It falls onto the blob, catapulting the second stick figure into the air. What is the maximum height to which the second stick figure can rise? Assume that stick figures, boulders, and blobs obey the law of conservation of energy.
