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 `0letle1` s is :

A

`(7)/(2) m//s `

B

`(9)/(2) m//s `

C

`4 m//s`

D

`5 m//s`

Text Solution

Verified by Experts

The correct Answer is:
3
`v_("av")= (intvdt)/(intdt) = (overset(1)underset(0) int (2t+ 3) dt)/( overset1 underset0 int dt) = ((t^(2) + 3t)_(0)^(1))/((t)_(0)^(1))= 4m//s `
