It is proposed to dispose of nuclear wastes- in drums with weight W=640 lbs and volume 8ft^3- by dropping them into the ocean v0=0.
It is proposed to dispose of nuclear wastes- in drums with weight W=640 lbs and volume 8ft^3- by dropping them into the ocean v0=0. The force equation of a drum falling in the water is m(dv/dt)=-W+B+Fr where the buoyant force B is equal to the weight (at 62.5 lb/ft^3) of the volume of water displaced by the drum (Archimedes' principle) and Fr is the force of water resistance found empirically to be 1 lb for each foot per second of the velocity of a drum. If the drums are likely to burst upon impact of more than 75 ft/s, what is the maximum depth to which they can be dropped in the ocean without likelihood of bursting?
