Four equal masses m are spaced at equal intervals (each of length d) along a horizontal, straight rod whose mass can be ignored. the system is to be rotated about a vertical axis passing through the mass at the left end of the rod and perpendicular to it.
(a) what is the moment of inertia of the system about this axis? (assume that each mass is a particle, with no finite size.)
(b) what minimum force, applied to the farthest mass, will give the system an angular acceleration?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
