You push a crate of mass 27 kg 15 m up a ramp
that is sloped 19° above the horizontal. The coefficient
of kinetic friction between the ramp and the crate is
0.15, and the speed of the crate, which starts from rest, is
1.7 m/s at the end of the 15 m. To accomplish the task,
you apply a variable force directed along the ramp.
(a) Calculate the change in the crate’s gravitational
potential energy (crate–Earth system).
(b) Calculate the work done by the applied force.

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...

Chewbacca is pushing a 250 kg crate up a ramp, which is 26 degrees above the horizontal, into the Millenium Falcon. He managed to push the crate 11.4 m up the ramp when he spots some enemy bounty hunters. Chewbacca tries to defend himself by shooting at them and the crate starts sliding down the ramp. The coefficient of kinetic friction is 0.45. What is the work due to kinetic friction on the crate? What is the gravitational potential energy...

A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30.0 ◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress...
