If velocity of a particle is given by v=...

If velocity of a particle is given by `v= (2t+3) m//s` then average velocity in interval `0 le t le 1`s is :

A

`7/2 m//sec`

B

`9/2 m//sec`

C

`4 m//sec`

D

`5 m//sec`

Text Solution

Verified by Experts

The correct Answer is:
C
`V=2t+3`
as v is linear function of time t
`v_(avg)=(v_(i) +v_(f))/(2)`
`=(v_(t=0)+v_(t=1))/(2)`
`=(3+5)/(2)=4 4 m//sec`
