A student on a piano stool rotates freely with an angular speed of 2.97 rev/s. The student holds a 1.32-kg mass in each outstretched arm, 0.797 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 5.35 kgm2, a value that remains constant. As the student pulls his arms inward, his angular speed increases to 3.46 rev/s. How far are the masses from the axis of rotation at this time, considering the masses to be points

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t 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?
