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
**Please answer this to the best of your ability, I've been having a lot of trouble with it

A boat with a mass of 500kg is initially moving at a speed of
20m/s east (+). The kinetic friction force between the hull of the
boat and the water has a coefficient of kinetic friction of
m=0.05?
Part A) What is the magnitude and direction of the kinetic
frictional force acting on the boat?
Part B) Oars are then extended and used so that the oars provide
a force, F= 503N, in a direction that is 20° south of...
