Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 45 degrees from the horizontal. The rope pulls on block 1 with a force of 360 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.2. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. What is the magnitude of the...
A mass m = 14 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.12, for a
distance d = 5.9 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 38° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 38°

A mass m = 15 kg is pulled along a horizontal floor with NO friction for a distance d =7.1 m. Then the mass is pulled up an incline that makes an angle θ = 30° with the horizontal and has a coefficient of kinetic friction μk = 0.38.

A 0.30 kg block is pulled up a 25 degree incline by an ideal string under tension; the string is draped over an ideal pulley. Tension in the string is created by a second block of equal mass, suspended by the section of the string directly below the pulley. The coefficient of friction between the first block and the incline is 0.40. After a slight push, what would be (a) the acceleration of the blocks, and (b) the tension in...
A block (m1 = 3.7 kg) is being pulled up a ramp (at an angle = 36.4 degrees from the horizontal) with a cable that is parallel to the ramp's surface. The cable runs over a pulley that is at the top of the ramp and then is attached to a hanging block (m2 = 17 kg). What is the tension in the cable? Assume that the coefficient of kinetic friction for the block on the ramp is 0.2.
