As a cork rises through a viscous liquid by buoyant forces, its acceleration:
A. Stays constant.
B. Decreases from initial value due to viscosity
C. Increases from initial value due to increasing kinetic energy
D. Decreasing from initial value due to decreasing potential energy
Answer: B.
I typed this, walked to bathroom and realized the answer. The realization is that viscosity is just like air resistance. More air speed entails more air resistance which lowers acceleration.
So. Enjoy.
