3. [1/3 Points] DETAILS PREVIOUS ANSWERS OSUNIPHYS1 10.7.P.085. MY NOTES ASK YOUR TEACHER Suppose you exert a force of 222 N tangential to a 0.275 m radius 75.0 kg grindstone (a solid disk). (Give your answers to at least 2 decimal places.) (a) What torque (in N . m) is exerted? (Enter the magnitude.) 61.05 N . m (b) What is the angular acceleration (in rad/s2) assuming negligible opposing friction? (Enter the magnitude.) 21.49 * rad/s2 (c) What is the angular acceleration (in rad/s ) if there is an opposing frictional force of 20.6 N exerted 1.25 cm from the axis? (Enter the magnitude.) 21.9 x rad/s2 Additional Materials Reading
