7 kg 3 kg 53° 49° There is no friction in the system above except between the rope and the pulley so that the rope does not slip on the pulley. The pulley is a uniform spherical shell with a mass of 1.43 kg and radius of 12 cm, and the rope does not slip on the pulley. The system is released from rest. Use work-energy principles to determine how much kinetic energy does the smaller mass have after moving d = 2.3 meters parallel to the ramp? K =

Small bodies of mass m1 and m₂ are attached to opposite ends of a thin rigid rod of length L and mass M. The rod is mounted so that it is free to rotate in a horizontal plane around a vertical axis (see below). What distance d from m₁ should the rotational axis be so that a minimum amount of work is required to set the rod rotating at an angular velocity w? (Use any variable or symbol stated above as necessary.) d= m₁ -L-d MY NOTES m₂
