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 67.0 kg, and the height of the water slide is 12.7 m. If the kinetic frictional force does -5.80 103 J of work, how fast is the student going at the bottom of the slide.
A 41 kg crate, starting from rest, is pulled across a floor with the constant horizontal force of 250 N. For the first 10m the floor is frictionless, and for the next 11.00 m the coefficient of friction is 0.17. What is the final speed of the crat..
