Q.
The variation of velocity of a particle moving along a straight line is shown in the figure. The distance travelled by the particle in 4s is
A) 25 m
B) 30 m
C) 55 m
D) 60 m
Explanation
(c) $S = \frac{1}{2} \times 1 \times 20 + 1 \times 20 + \frac{1}{2} \times (20 + 10) \times 1 + 1 \times 10$
$= 55$m
