The position-time graph of a particle of...

The position-time graph of a particle of mass 4 kg is shown in the figure. Calculate the impulse (in MKS units) at time t = 0 and t=6 second respectively.

A

`+ .6 31and − .6 31`

B

`+ .3 33and − .3 33 `

C

`+ .5 25 and − .5 25`

D

`+ .3 25 and − .3 25`

Verified by Experts

The correct Answer is:

B

Impulse (I) = Change in momentum
At t = 0
`I = ((5)/(6) - 0) xx 4 (20)/(6) = 3.33`
at t = 6
`I = (0 - (5)/(6)) xx 4 = - 3.33`
