A wheel rolls to the right with an angular velocity of 2 rad/s while slowing down at a rate of 3 rad/s^2.. knowing the wheel rolls without sliding and ignoring the effect of gravity determine the location on the wheel where the net acceleration is zero. Provide your answer in terms of x,y coordinates with 0,0 being at the wheel's center.
