A small steel ball is dropped into a long cylinder containing glycerine. Which one of the following is the correct representation of the velocity–time graph for the transit of the ball?
Answer: (B) see figure
The ball starts from rest. As its speed increases, the viscous drag increases, so the acceleration keeps falling. The velocity rises and levels off at the terminal velocity, where weight = buoyancy + drag.
This is the curve rising from zero and flattening out: graph (2).
