If an object has a moment of inertia 29 kg.m and the magnitude of its rotational angular momentum is 86 kg . m2/s, what is its rotational kinetic energy? Krot = JA disk of radius R = 10 cm is pulled along a frictionless surface with a force of F = 21 N by a string wrapped around the edge. d F At the instant when d = 29 cm of string has unwound off the disk, what is the torque exerted about the center of the disk? Tic: N-m
