A force-time graph for the motion of a body is shown in the figure. The change in the momentum of the body between zero and 10sec is

A

`zero`

B

`4kgm//s`

C

`5kgm//s`

D

`3kgm//s`

Text Solution

Verified by Experts

The correct Answer is:
D
As `F=(dp)/(dt)`
`intdp=intFdt`
`Deltap` =area under `F-t` graph
`Deltap=(1)/(2)xx8xx1-2xx8.5=3kgm//s`
