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 worker pushes a 100 kg crate upward a distance 5.0 m along a frictionless conveyer that makes an angle of 30 degrees with the horizontal. The force she exerts is parallel to the conveyer. If the speed of the crate is constant, the work done by the worker is A 250 J B -2,500 J C 2,500 J D 500 J E -250 J F -500 J

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...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....
