John is sitting ( at rest) at the top of a slide that is inclined 25 deg with respect to the horizontal. After travelling 5.0 m, (the length of the slide), John's speed at the bottom of the slide is 5.4m/s. Assume that the friction is not negligible in this situation. If John's mass is 25 kg, how much does the thermal energy increase during John's trip down the slide?
