Suppose you exert a force of 181 N tangential to a 0.286-m-radius 79.4-kg grindstone (a solid disk). a. What torque is exerted? T= N.m b. What is the angular acceleration assuming negligible opposing friction? α= rad/s² c. What is the angular acceleration if there is an opposing frictional force of 20.5 N exerted 1.51 cm from the axis α = rad/s²
