Bob the minion drops a tennis ball atop a poorly inflated basketball from a height of 5.38m above the ground. The mass of the teniss ball is 0.18 times the mass of the basketball. The poorly inflated basketball stays on the ground when it hits the ground but the tennis ball flies up high into the air! When the balls hit the ground only 1/4 of their energy goes into the tennis ball. Using Energy, predict the maximum height (in m) that the tennis ball could reach.
