A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force (a nonconservative force) acts on her. The student has a mass of 71.0 kg, and the height of the water slide is 12.0 m. If the kinetic frictional force does -7.60 10^3 J of work, how fast is the student going at the bottom of the slide?
