Calculate the work done by the force below if F0= 150 N. In a sentence or two, explain how did you calculate the work?

A force, varying with distance as shown in the graph below, acts on a 5.5 kg object. When is most work done, in the first 4 meters or between 4 and 6 meters? Explain your response. a. 4.0 3.0 2.0 1.0 b. Find the work done by the force in moving the object from 0 m to 6.0 m. Explain your calculation and give units. 2.0 4.0 6.0 8.0 Positien Cr Figure 9-15 Assuming that there is no friction or air resistance what is the total change in the object's energy? Explain your answer. с. kinetic FORCE (N)

mike used his super muscle power to pull a box initially at rest, up an inclined plane. The inclined plane makes an angle of 35o with the horizontal and mike applied a force of 250 N parallel to the incline. The mass of the box is 25.0 kg and the coefficient of kinetic friction between the box and the surface is 0.45. The box moves up the incline at a distance of 5.0 m.  Find the work done by the applied force.    g = 9.81 m/s2

Calculate the work done (in J) by an 80.0 kg man who pushes a crate 3.65 m up along a ramp that makes an angle of 20.0° with the horizontal. (See the figure below.) He exerts a force of 550 N on the crate parallel to the ramp and moves at a constant speed. Be certain to include the work he does on the crate and on his body to get up the ramp. F
