When the child slides down to the bottom of the slide, her KE = 300.0 J. a) What was the height of the slide?b) How much was the work done by friction?c) How fast was the child moving when she reached the middle of the slide? (Assume that thework done by friction is half of what you get in (b). Note that the PE2 is not zero this time.)
