The wheel has mass m, radius R and moment of inertia IG = mR2/2. The wheel is initially at rest, and it is subjected to a pair of forces with equal magnitude F and opposite directions as shown. When the wheel rolls without slipping, the coefficient of friction between the wheel and the floor is μs = .5. When the wheel rolls and slips, the coefficient of friction between the wheel and the floor is μk = .3. Find the acceleration of the center of the wheel if
