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?

A 4.41-g bullet is moving horizontally with a velocity of +354 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1199 g, and its velocity is +0.644 m/s after the bullet passes through it. The mass of the second block is 1576 g . (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision. (a) Before collision (b) After collision (a) vblock2 = Number Units (b) KEafter/KEbefore = Number Units

A hanging weight, with a mass of m1 = 0.360 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is μk = 0.250. At the instant shown, the block is moving with a velocity of vi = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s ) after it has moved a distance of 0.700 m away from the initial position shown. m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? rad/s
