Problem 14: The diagram shows a crate with mass m = 20.1 kg being pushed up an incline that makes an angle φ = 15 degrees with horizontal. The pushing force is horizontal, with magnitude P = 450 N. Starting from rest, the crate achieves a speed of 4.01 m/s as it moves a distance d = 4.01 m. What is the work done by friction, in joules? W = J

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.
