M, a solid cylinder (M=2.43 kg, R=0.123 m) pivots on a thin,
fixed, frictionless bearing. A string wrapped around the cylinder
pulls downward with a force F which equals the weight of a 0.770 kg
mass, i.e., F = 7.554 N. Calculate the angular acceleration of the
cylinder.
If instead of the force F an actual mass m = 0.770 kg is hung from the string, find the angular acceleration of the cylinder. M m 3.09x101 rad/s^2 You are correct....
