The crate shown in Figure Q1.2 has a mass of m kg and is being raised up a plane at θ degrees by cable parallel to the plane. The coefficient of friction is μ. FIGURE 1.2 Note that values for m, θ and μ are randomly generated. Calculate the magnitude of the tension, T, that will allow an acceleration of a m/s2 up the plane. Note: the value for a is randomly generated. Given that the mass is initially at rest, what is its velocity after it has moved a distance of s m along the plane? Assume that the mass remains on the incline during this motion. Note: the value for s is randomly generated. Note also: constant acceleration can be assumed. What is the work done after the mass has moved a distance of s m?

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.
