Buoyancy and terminal velocity

Reference no: EM13126914

Archimedes principal of buoancy states that an object submerged in a fluid is buoyed up by a force equal to the weight of the fluid the object displaces.

A rectangular box 1foot X 2 feet X 3 feet and weighing 384 lbs. is dropped into a 100 foot deep freshwater lake (density 62.4 lbs/cubic foot). The box immediately begins to sink. The drag due to the water is 1/2 the velocity.

Calculate the following:

a) the terminal velocity

b) the velocity when the box reaches the bottom
