(10%) Problem 8: An object with an MOI of 0.0497 kg - m? rotates freely about a particular axis. The object is initially at rest, but the application of an angle-dependent torque causes it to rotate about that axis. The graph below displays the torque, in millinewton meters, versus the angular position, in revolutions. +300. +200. +100. 0.00 2.00 3.00 .00 1.00 7 (mN - m) 100. 200. 300. 8 (rev) = 2.31 rev?
