A particle starts from rest x = - 2.25 m and moves along the x - axis with the v - t graph as shown. The time when the particle crosses the origin is :

A

0.5 s

B

1 s

C

1.5 s

D

2 s

Text Solution

Verified by Experts

The correct Answer is:
B
When particle reaches the origin, then
`s = vec(x)_(f) - vec(x)_(i) = 2.25m`
So, area of v-t curve = 2.25 m
