A block of 3 kg is moving up on a ramp (by initial push). The angle of the ramp is 40 degrees. The coefficient of kinetic friction is 0.25. Calculate the acceleration of the object.
Th figure below shows a mass m=1.0 kg which is initially moving with speed v=7.2 m/s at the top of a frictionless hill of height h=4.9 m. It slides down the hill until it encounters a flat section with unknown coefficient of kinetic friction µk. If the object travels a distance D=11.1 m before reaching a speed of v/2, what is the coefficient of kinetic friction µk? (use picture, but first question) Th figure below shows a mass m=1.0 kg...

Two blocks, connected together by a thin but strong cord, are placed on a ramp as shown in the figure. The angle of the ramp is ?=30 degrees , the masses of the blocks are mA = 1.00kg and mB = 2.00kg, and the coefficient of static and kinetic friction between boxes and ramp are µs = 0.500 and µk = 0.200. The gravitational acceleration is 9.8m/s2 . The mass of the cord is negligible. The cord does not stretch...

A m = 10.0 kg box slides down a d = 00 m long ramp that is raised h = 0 .500 m above the ground (thus the ramp has a θ = 30.0⁰ incline). Assuming the ramp has a coefficient of kinetic friction of µk = 0.200 and the box is initially at rest, what is the final speed of the box when it makes it to the bottom of the ramp?
