Can anyone help me get started with this problem:(adsbygoogle = window.adsbygoogle || []).push({});

A 50kg man at a water park shows off by going down a long, winding waterslide of varying slope. THe slide is a total of 25m tall from start to finish, and the man starts from rest. DEspite all the attempts to minimize friction with rushing water, there remains some friction between the man and the slide. If he shoots out of the end of the slide at only 8.0m/s instead of the speed you found in part (a) how many joules of energy were dissipated by friction on his way down? what percentage of his initial total energy does this represent?

THANKS!!
