A 55.6 kilogram kid slides down a water slide with a velocity of 0.9 m/s at the top. At the bottom of the slide, he is moving horizontally, y=1.5 m above the water. He splashes into the water d =2 m to the left of the bottom of the slide. Assuming potential energy to be zero at the water level, obtain the mechanical energy of the kid at the top of the slide?
Find how high is the top of the slide above the bottom of the slide?
