A 10-kg kid comes down a slide. The slide is 3 meters high and 5 meters long. The slide also has a frictional force of 10 N that acts along the entire length of the slide. How fast is the kid going when he reaches the bottom? HINT 1: What is the total amount of energy that the kid has at the top and should have at the bottom? HINT 2: By how much does friction change that energy? HINT 3: What type of energy does the kid have at the bottom vs. the top?
