Sliding downA child slides down a 3 m high slide. The slide is at a 40o angle from the horizontal. Upon reaching the bottom, her kinetic energy is two-thirds of what it would have been if there was no friction. What is the coefficient of friction?
In this exercise you will practice the first part of solving the above problem. In the energy graphs below, adjust the amount of energy so that the diagram reflects qualitatively the relative values for gravitational potential energy (GPE), kinetic energy (KE), and internal (IE, thermal from friction) energy.
(Help on graphing.)
