The smaller disk has a mass of 0.95 kg and radius of 38 cm. The largerdisk has a mass of 3 kg and radius of 76 cm. The pulley is mounted on africtionless axle that runs through the center of the smaller disk and the midpointbetween the center and edge of the larger disk. A rope is wrapped around thesmaller disk such that it does not slip. Use work-energy principles to determinehow far the hanging mass has fallen when the kinetic energy of the pulley is 250 J,if the system started at rest.d =m

A 70 kg secret agent skis down a hill and grabs a 200 kg bag then flies off a 12 m high cliff. The hill can be considered a 1/4 of a circle with a radius of 20 m. a) The initial mechanical energy of the agent at the top of the hill is 14,560 J relative to the location of the bag. If the average force of friction is 120 N determine the velocity of the agent before he picks up the bag. B) what is his apparent weight right before he picks up the bag? C) how fast is the agent traveling after he grabs a bag? D) how far from the base of the cliff does the agent land? Assume the resistance is negligible. E) Assume that the agent in his bag come to rest upon colliding with the ground at the base of the cliff. What is an impulse that he in the bag experiences? Estimate the resulting contact force on the agent. Discuss the likelihood of his living through the collision.
