A water wheel is being used to mill flour. After loading the grain in the mill the wheel is started from rest. The grain mill accelerates to an angular velocity of 2 rad/sec in 5 sec. At the instant that the mill is rotating at 1.5 rad/sec, what is the acceleration in vector form, of a grain at a radius of 1.77 meters from the center of the mill
