A
5.0 kg hollow cylinder of radius 0.28 m rotates freely about an
axle that runs through its center and along its long axis. A cord
is wrapped around the cylinder and is pulled straight from the
cylinder with a steady tensile force of 50N. As the cord unwinds,
the cylinder rotates, with no slippage between the cord and the
cylinder.
A) calculate the work done by the tensile force as the
cylinder rotates through 1000 rad.
B) if the cylinder starts from rest, calculate the roatational
speed after it has rotated through 1000rad.
