A student of mass 59.4 kg, starting at rest, slides down a slide 23.2 m long, tilted at an angle of 28.1° 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) N (b) the acceleration (in m/s2) m/s2 (c) the speed she is traveling (in m/s) m/s   HINTS: (a) First, find the normal force acting on the student and use that value to calculate the kinetic friction force. (b) Find the acceleration using the tilted x-component of Newton's second law. (c) Use kinematics to find her speed at the bottom of the slide.
