Question

A student of mass 60.0 kg, starting at rest, slides down a slide
20.0 m long, tilted at an angle of 30.0° with respect to the
horizontal. If the coefficient of kinetic friction between the
student and the slide is 0.120, find (a) the force of kinetic friction,
(b) the acceleration, and (c) the speed she is traveling
when she reaches the bottom of the slide.
