Ball `A` of mass `1`kg moving right with speed `2m//s` bounces off ball `B` of mass `1.5kg`, and then moves left with speed `4m//s`. Calculate magnitude of impulse (SI Units) received by ball `B`

`2`

`3`

`6`

`4`

Text Solution

Verified by Experts

The correct Answer is:

Ans.(3)
impulse on `A=-` impulse on `B`
`vec(P)=2hat(i),vec(P_(f))=-4hat(i)`, Impulse on `A=-6hat(i)`
`rArr` Impluse on `B=6hat(i)` Ns
