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...
You push a crate of mass m up a ramp inclined at an angle A with...
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)...
