A cylindrical buoy at the entrance of a harbor has a diameter of 0.9 m and a height of 2.6 m. The mass of the buoy is 600 kg. It is attached to the bottom of the sea with a nylon cable of negligible mass. The specific gravity of the seawater is 1.025.

(a) How much of the buoy is visible when the cable is slack?

(b) If a tidal wave completely submerges the buoy, what is the tension in the taut cable?

(c) If the cable breaks, what is the initial upward acceleration of the buoy?
