13. The same force F is ap- plied to the edge of two hoops (see the drawing). The hoops have the same mass, whereas the radius of the larger hoop 2R is twice the radius of the Axis smaller one. The entire mass Axis of each hoop is concentrated at its rim, so the moment of inertia is I = Mr, where M Mass = M Mass = M is the mass and r is the radius. Which hoop has the greater angular acceleration, and how many times as great is it compared to the angular acceleration of the other hoop? (a) The smaller hoop; two times as great (b) The smaller hoop; four times as great (c) The larger hoop; two times as great (d) The larger hoop: four times as great (e) Both have the same angular acceleration.

A massless string is wrapped around a solid 7.6-kg cylinder of diameter 24 cm that can rotate freely withoutfriction about an axis through its center. A stone is tied to the loose end of the string. When the stone isreleased from rest, the cylinder turns without the string slipping. If the cylinder has an angular velocity of26 rad/s after 1.4 s, what is the mass of the stone? Through how many revolutions does the cylinder turn inthis time?
