Aturntable spins up from rest with an angular acceleration of 1.0 rad/s2. a rubber eraser of mass 20 g with coefficientof static friction 1.0 is at a distance of 0.1 m from the center of the turntable, when it begins to spin. how long does ittake for the eraser to begin to slide off the turntable? note that the tangential acceleration of the eraser is very small.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
