A steel ball is dropped in a viscous liquid. The distance of the steel ball from the top of the liquid is shown below. The terminal velocity of the ball is closest to

Step-by-step solution

Velocity = Slope of distance - Time graph Last portion of given graph is a straight line which indicates that velocity is constant, i.e. terminal velocity is reached. From data of graph, Terminal velocity, v = x 2 - x 1 t 2 - t 1 = 0 . 4 - 0 . 3 1 . 9 - 1 . 6 = 0 . 1 0 . 3 = 0 . 33 m / s
