A low-mass rod of length 0.44 m has a metal ball of mass 1.8 kg at each end. The center of the rod is located at the origin, and the rod rotates in the xy plane about its center. The rod rotates counterclockwise around its axis when viewed from a point on the z axis, looking toward the origin. The rod makes one complete rotation every 0.7 s.
Required:
a. What is the moment of inertia of the object (rod plus two balls)?
b. What is the rotational angular momentum of the object?
c. What is the rotational kinetic energy of the object?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you donβt find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
