Question

Consider the following Scenario: a child climbs to the top of the slide for which friction is not negligible. The child then slides from rest down the slide, going up and over a small bump, then continues down before leveling off and eventually coming to a stop at the very end of the slide. a.) Identify the forms of energy the child has during this scenario? b.) explain how they are changed and transfered during these events? c.) what would change if the top of the slide was higher, making the entire slide steeper? d.) what would change if the slide was coated in an experimental treatment that made the slide frictionless?

Explanation / Answer

a) gravitational Potential energy , Kinetic energy , Frictional loss
b) Potential energy is decreased during process which provide frictional loss and Kinetic energy

c) Initial Potential energy will be higher and boy will have some Kinetic energy at the bottom of slide

d) There will be no frictional loss and all of potential energy will change in Kinetic energy and boy will have a speed and Kinetic energy atbottom of slide
