1. A disk rotating about its axis uniformly accelerates from rest to 4.8 rad/s in 3.4 s. The net torque exerted on the wheel is 2.6 N.m. Find the moment of inertia of the wheel. a= 4.9 rad /s. in 3 . 4 5. O I = 2.6 NM 4.8 = 1 1412 3. 2. Find the total kinetic energy of the rolling 2.4-kg cylinder if its center of mass moves at 2.8 m/s. The radius of the cylinder is 0.76 m. Hint: 1 = (1/2)MR2
