m= 0.0011kg

r=0.84/2

Fc=3.9N but when I plug all that into the equation, I'm being told it's wrong. What am I missing?

An adapted golf device attaches to a wheelchair to help people with mobility impairments play putt-putt. The stationary frame OD is attached to the wheelchair, and a club holder OB is attached to the pin at O. Holder OB is 6 in. long and weighs 8 oz, and the distance between O and D is x = 1 ft. The putter shaft has a length of L = 36 in. and weighs 10 oz, while the putter head at A weighs 12 oz. Knowing that the 1-lb/in. spring between D and B is unstretched when 0 = 90° and that the putter is released from rest at 0 = 0, determine the putter head speed when it hits the golf ball.
