As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...

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 block starts from rest and slides down a smooth ramp of height h. When it reaches the bottom it is moving at speed v. It then continues to slide up a second smooth ramp. What is the velocity up the second ramp at the point the potential energy is equal to the kinetic energy? 1. v/2 2. v/3 3. v/4 4. v 5. sqrt(3)v/ 6. sqrt(2)v/
