A person starts from origin and for his linear motion velocity is given as shown in figure. Fond displacement of the person from `t=15 sec` to `t = 35 sec`.
.

A

75 m

B

0

C

`-75 m`

D

150 m

Text Solution

Verified by Experts

The correct Answer is:
B

Area under velocity time graph gives displacement.
`S=underset(t_(1)) overset(t_(2))(int) vdt = underset(15)overset(35)(int) vdt`
`=(1)/(2)xx(25-15)xx15-(1)/(2)(35-25)xx15`
`S=75 -75 =0`.
