A 50.2 kg child slides down a water slide with a velocity of 1.1 m/sec at the top. At the bottom of the slide, she is moving horizontally, 1.5 meters above the water. She splashes into the water 2.5 meters to the right of the bottom of the slide.

a) Assuming potential energy to be zero at the water level, what is the mechanical energy of the child at the top of the slide? MEo=

b) How high is the top of the slide above the bottom of the slide?
