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 81 kg, and the height of the water slide is 11.7 m. If the kinetic frictional force does -6.7 × 103 J of work, how fast is the student going at the bottom of the slide?

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 81.0 kg, and the height of the water slide is 10.9 m. If the kinetic frictional force does -7.70 × 103 J of work, how fast is the student going at the bottom of the slide?

4. A student, starting from rest, slides down a water slide. On the way down, a kinetic frictional force "A non-conservative force" acts on her. The student has a mass of 76 kg, and the height of the water slide is 15.0 m. If the kinetic frictional force does - 6.2 x 10 J of work, How fast is the student going at the bottom of the slide?

9 The ball is allowed once more to slide down the slide-slot, starting at rest from point R. However, this time the slide-slot is unconstrained horizontally so that it is free to slide on the table. While sliding, the ball is always in contact with the slide-slot. The mass of the slide-slot is 500 g. gravitational acceleration (g) of a free-falling object is 10 m s-2. As the ball slides down the curved surface, from point R to point T,...
