6. A water slide can be considered to be frictionless. The topof the slide is 4.2 m above the bottom of the slide. Riders exitthe slide with a horizontal velocity. The bottom of the slide is1.5 m above the water. A certain rider has a mass of 27 kg.
A. Sketch the situation at the top of the slide, bottom if theslide, and just before they hit the water.
B. What is their gravitational potential energy at the top ofthe slide, relative to the bottom of the slide and relative to thetop of the water?
C. What is their kinetic energy and speed at the bottom of theslide?
D. How far do they travel horizontally from the bottom of theslide before they hit the water?
E. Does the horizontal distance traveled depend on the mass ofthe rider? Explain.
