A container full of explosives is sliding down a hill toward a village at 50.0 m/s. The container and explosives have a total mass of 7.50×104 kg. Two superheroes arrive at the same time and begin pushing on the container to stop it. The flying superhero pushes horizontally with a force of 2.00×105 N. The standing superhero pushes up the slope with a force of 2.00×105 N. They manage to stop the container in 200 m. The hill has a constant slope of 40.0∘ relative to the horizontal. a. Use the work-energy theorem (chapter 7 style) to find the net work done on the container. b. Use the definition of work to find the work done by each of the forces listed. (The force from the flying superhero, the force from the standing superhero, the force of gravity, and the normal force) c. How much work must have been done by kinetic friction? d. How strong was the kinetic frictional force? e. What was the coefficient of kinetic friction?

The block has a mass of 0.5 kg and moves within the smooth vertical slot. If the block starts from rest when the attached spring is in the unstretched position at A, determine the constant vertical force F which must be applied to the cord so that the block attains a speed vB = 5 m/s when it reaches B; sB = 0.25 m. Neglect the mass of the cord and pulley. a. (5 points) Establish a coordinate system, specify the direction and sense of the forces, displacement, velocity, etc. b. (10 points) Select a position between A and B. Draw the free-body-diagram. c. (10 points) List the forces doing work on the block when it moves from A to B. d. (5 points) Calculate the kinetic energy of the black when it arrives at B. e. (20 points) Use the principle of work and energy to solve for the constant vertical force F. Hint: when the block moves from A to B, how far does F travel in its direction? How much work does it do?
