A tuna with a mass of 100kg swims at a level depth of 20m below the surface of the sea.
1) Draw a free body diagram for the tuna.
2) Calculate the buoyant force on the tuna, and with that the tuna’s volume.
3) Some fish are able change their volume in order to move up and down by inflating a specilized organ within them called a swim bladder. Calculate how much the volume of the tuna must be changed in order for the buoyant force to grow by 30N.
4) By modeling the tuna as a spherical object, estimate the resultant upward terminal velocity of the tuna in this case
