A student is at rest at the top of a playground slide. The length of the slide is 5.0 m long, and it is at an angle of 30 degrees. When the student leaves the slide he is traveling at a speed of 2.0 m/s. The student's mass is 24.0 kg. a. (3 points) What is the student's initial total energy? 30 b. (3 points) What is the student's final total energy? c. (3 points) Based on this, what is the force of friction (NOT coefficient) of the slide on the student? (consider the thermal loss in the system.)
