5. (6 pts.)Three cylinders are rolled down an inclined plane, starting together from rest. Cylinder A is made of brass and has mass M, radius R and length , cylinder B of wood also of mass M and radius R but longer length L, cylinder C is made of brass and is hollowed out to have same mass M and radius R but length L. Which of the following is true for the order in which they reach the ground first?
6. (6 pts.)A man stands on a platform that is rotating (without friction) with an angular speed of 1.2 rev/s. His arms are outstretched and he holds a brick in each hand. The rotational inertia of man, bricks and platform about the central, vertical axis is 6.0 kg m2.If, by moving the bricks the man decreases the rotational inertia of the system to 2.0 kg m2, what is the change is the rotational kinetic energy?
7. (6 pts.)The figure shows three forces applied to a thin meter stick (massless) that is in equilibrium. What is the magnitude of force F1? A. 5 N B. 10 N C. 20 N D. 40 N E. not enough information
8. (6 pts.)The figure shows plots of the kinetic energy versus position for three harmonic oscillators that have the same mass. Rank the plots according to the periods of the oscillators, greatest first. A. A > B > C B. C > B > A C. B > A > C D. B > C > A E. all have same period xmxmK A B C x
9. (6 pts.)At a circus, a clown on a motorcycle with a mass Mtravels along a horizontal track and enters a vertical circle of radius r. Which one of the following expressions determines the minimum speed that the motorcycle must have at the top of the track to remain in contact with the track?
