CAIE A-Level Physics AS 3.2.3 Objects Moving Against a Resistive Force May Reach a Terminal Constant Questions question 1

[Maximum number: 2]

The cylinder in (b) is released from the string at time t=4.0 st=4.0 \mathrm{~s}. The cylinder falls, from rest, vertically downwards through the water. Assume that the upthrust acting on the cylinder remains constant as it falls.

State and explain the variation, if any, of the acceleration of the cylinder as it falls downwards through the water.
