Moving at an initial speed of vi = 2.00 m/s, Jimmy slides from a height of h = 5.00 m down a straight playground slide, which is inclined at θ = 55° above the horizontal. At the bottom of the slide, Jimmy is moving at vf = 9.00 m/s. By determining the change in mechanical energy, calculate the coefficient of kinetic friction between Jimmy and the slide.
