A student of mass 55.4 kg, starting at rest, slides down a slide 21.2 m long, tilted at an angle of 32.1° with respect to the horizontal. If the coefficient of kinetic friction between the student and the slide is 0.113, find the force of kinetic friction, the acceleration, and the speed she is traveling when she reaches the bottom of the slide. (Enter the magnitudes.) (a) the force of kinetic friction (in N) (b) the acceleration (in m/s2) (c) the speed she is traveling (in m/s)

(a)
the force of kinetic friction (in N)
(b)
the acceleration (in m/s2)
(c)
the speed she is traveling (in m/s)
We are given mass of student. We are also given angle of slide on which student slides. We are given friction coefficient. We first find frictional force. We then find net force and acceleration. We then find final speed of student at bottom of slide.
