Figure 1 Robin is pushing a crate up an inclined plane. Robin pushes with a force of FRC which is parallel to the plane. Robin moves the crate a distance d (measured parallel to the plane). There is ordinary surface friction between the crate and the plane. This question refers to the situation shown in Figure 1, above. Robin pushed the crate with a constant force and the crate moved at constant speed. The crate moved a distance d = 3.37 meters. The crate has a mass of 21.5 kg and the plane is inclined at an angle of 38.5 degrees above horizontal. The coefficient of kinetic friction between the crate and the plane is 0.22 . Assume the only forces acting on the box are the force exerted by Robin, the forces exerted by the inclined plane (this includes friction), and gravity (with g = 9.81 m/s2. Calculate the work done (in units of joules) on the crate by the inclined plane via the friction force (and only via the friction force) as the crate moved a distance d. (The sign of your answer, positive or negative, is important.)Figure 1 Robin is pushing a crate up an inclined plane. Robin pushes with a force of FRC which is parallel to the plane.

part 1 of 2 A block of mass 1 kg and one of mass 7 kg are connected by a massless string over a pulley that is in the shape of a disk having a radius of 0.39 m, and a mass of 9 kg. In addition, the blocks are allowed to move on a fixed block-wedge of angle 31∘, as shown. The coefficient of kinetic friction is 0.25 for both blocks. What is the acceleration of the two blocks? The acceleration of gravity is 9.8 m/s2. Assume the positive direction is to the right. Answer in units of m/s2. part 2 of 2 Find the tension in the horizontal part of the string. Answer in units of N.

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.
