A box sits on a 30o incline as shown below, and is coasting up the ramp with an initial speed of 5.0 m/s. The coefficient of kinetic friction between the box and the ramp is 0.25. Determine the acceleration of the box on the way up. How long will it take for the box to come to rest? How far up the ramp will it travel before coming to rest?

Please explain steps for part d. I cannot figure it out A box, with a weight of mg = 25 N, is placed at the top of a ramp and released from rest. The ramp measures 4.20 meters horizontally and 3.30 meters vertically. The box accelerates down the incline, attaining a kinetic energy at the bottom of the ramp of 48.0 J. There is a force of kinetic friction acting on the box as it slides down the incline. a)...

A sphere with a mass of 8kg and diameter of 25cm is initially on top of a ramp at rest with an angle of 30 degrees with a base length of 5 meters. The sphere rolls down the ramp with an initial velocity of 3 m/s. a) What is the final velocity of the sphere at the bottom of the ramp if the coefficient of friction is 0.3 [I=2/5 mr^2] b) Calculate the revolutions per second of the sphere from...

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...
