Suppose you exert a force of 180 N tangential to a 0.280-m-radius 75.0-kg grindstone (a solid disk). What is the angular acceleration if there is also an opposing frictional force of 20.0 N exerted 1.50 cm from the axis? (Hint: you need to calculate the total torque due to these two forces; calculate the grindstone's moment of inertia; and use Newton's 2nd Law for Rotations to get the angular acceleration.) 6.75 rad/s? 17.0 rad/s? 8.50 rad/s2 12.5 rad/s
