Q. A bird flies for $4\ s$ with a velocity of $|t - 2|m/s$ in a straight line, where $t$ is time in seconds. It covers a distance of
A) $2\ m$
B) $4\ m$
C) $6\ m$
D) $8\ m$
Explanation
(b) The velocity time graph for given problem is shown in the figure.
Distance travelled $S = Area\ under\ curve = 2 + 2 = 4m$
