A typical ten-pound car wheel has a moment of inertia of about 0.35 kg · m². The wheel rotates about the axle at a constant angular speed making 35.0 full revolutions in a time interval of 5.00 s.

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. The initial mechanical energy of the agent at the top of the hill is 14,560 J relative to the location of the bag.  his initial apparent weight is 2521 .4 N and initial velocity is 22.9 m/s 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

4. Two wheels (A and B) of equal mass and the same Iz roll down a hill without sliding and have the same kinetic energy.  Partway down the hill, wheel B stops rolling and continues down the hill sliding (no rotation), but maintains the same kinetic energy as wheel A which continues to roll without sliding.  Which wheel reaches the base of the hill first (assuming they travel the same path length)? wheel A (the one that rolls the whole way) wheel B (the one that starts sliding) they reach the hill base at the same time

I included two pictures. Please show me how to approach the problem in the correct manner based on the feedback given. It is okay to completely change the answer if you need to. Please give a reasoning to why the claim is not reasonable and the work needed to back this up.

The puck in the figure below has a mass of 0.186 kg. Its original distance from the center of rotation is 40.0 cm, and it moves with a speed of 85.0 cm/s. The string is pulled downward 15.0 cm through the hole in the frictionless table. Determine the work done on the puck. Hint: Consider the change in kinetic energy of the puck. Need Help?
