The position-time graph for a particle moving along a straight line is shown in figure. The total distance travelled by it in time t=0 to t=10 s is (A) Zero (B) 10 m (C) 20 m (D) 80 m

Tardigrade Admin · Accepted Answer

The total distance travelled from 0 to 2 s is 10 m 2 s to 8 s arrow Zero distance and from 8 s to 10 s arrow 10 m So, distance =10+0+10=20 m

Q. The position-time graph for a particle moving along a straight line is shown in figure. The total distance travelled by it in time $t = 0$ to $t = 10 s$ is

Zero

10 m

20 m

80 m

The total distance travelled from 0 to $2 s$ is $10 m$
$2 s$ to $8 s \to$ Zero distance
and from $8 s$ to $10 s \to 10 m$
So, distance $= 10 + 0 + 10 = 20 m$
