A spherical buoy used to mark the course for a sail- boat race is shown in the figure. There is a water current from left to right which causes a horizontal drag on the buoy; the effect of the current on the cable can be neglected.
The length of the cable between points A and B is 87 m, and the effective cable mass is 2 kg /m when the buoyancy of the cable is accounted for. Determine the tensions at both A and B.
