Oh I think I got it. 0.57:approve:

How do I set up an equation to solve for M and m?

Kinetic energy: 1/2mv2=1/2Iω2 Angular Momentum: (1/12MR2)(ω)= mv(1/4R)2 So do I set the equations equal to each other and then solve for M and m?

Homework Statement The figure below shows a thin, uniform bar whose length is L and mass is M and a compact hard sphere whose mass is m. The system is supported by a frictionless horizontal surface. The sphere moves to the right with velocity , and strikes the bar at a distance 1/4L from the...

Homework Statement Two objects, of masses m1 = 485.0 g and m2 = 494.7 g, are connected by a string of negligible mass that passes over a pulley with frictionless bearings. The pulley is a uniform 53.0-g disk with a radius of 4.08 cm. The string does not slip on the pulley. Find the...
