A bird flies for 4 seconds with a velocity of `|t-2|m//sec.` In a straight line, where `t=` time in seconds. It covers a distance of

A

`4m`

B

`6m`

C

`8m`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Plotting velocity `v` against time `t,` we get

Area under time `v-t` curve gives distanct.
Distance `=(1)/(2)xx2+(1)/(2)xx2xx=4m`
