A 1,440-N crate is being pushed across a level floor at a constant speed by a force F→ of 200 N at an angle of 20.0∘ below the horizontal, as shown in the figure a below. a b (i) (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) (b) If the 200−N force is instead pulling the block at an angle of 20.0∘ above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a). m/s2

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.

The figure below shows an object with mass m = 5.5 kg pulled up a plane inclined at an angle of θ = 27∘ with a force of magnitude F = 35 N parallel to the plane. (a) If there is no friction between the object and the plane, what is the magnitude of the object's acceleration (in m/s2)? m/s2 (b) If instead the coefficient of kinetic friction between the object and the plane is 0.12, what is the magnitude of the object's acceleration (in m/s2)? m/s2
