To solve this problem, we need to understand the motion of a spherical ball in a viscous liquid.$\\$When the ball is dropped, it initially accelerates due to gravity. However, as it moves through the liquid,$\\$it experiences a viscous drag force that increases with speed. Eventually, the ball reaches terminal velocity,$\\$where the gravitational force is balanced by the drag force, and the acceleration becomes zero.$\\$The speed-time graph for this motion should show:$\\$• An initial increase in speed as the ball accelerates.$\\$
