A child slides from rest down a playground slide. The top and bottom of the slide are separated by Ag 2 4.0m vertically and A11: 2 7.0m horizontally. A sheet of metal (straight, not curved) connects the two ends of the slide, and the coeicient of friction between the slide's surface and the child's clothes is me = 0.22. What is the child's speed '1: upon reaching the bot- tom of the slide? For the limits check, investigate what hap- pens to of as the slide becomes dangerously steep (A2: } 0). Note: you must use a work/energy approach rather than a kinematics approach to solve this problem.
