A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a non-conservative force) acts on her. (a) Does the kinetic frictional force do positive, negative, or zero work? Provide a reason for your answer. (b) Does the total mechanical energy of the student increase, decrease, or remain the same as she descends the slide? Why? (c) If the kinetic frictional force does work, how is this work related to the change in the total mechanical energy of the student? The student has a mass of 83.0 kg and the height of the water slide is 11.8 m. If the kinetic frictional force does
