Suppose your mass is 50 kg, how fast should you run so that your linear momentum become equal to that of cycle rider of 100 kg moving along a straight road with a speed of 20 km/h?

`40m//s`

`20km//h`

`11.11m//s`

`10.00km//h`

Text Solution

Verified by Experts

The correct Answer is:

Your momentum = momentum of cycle rider
`m_(1)v_(1)=m_(2)v_(2)`
`therefore v_(1)=v_(2)xx(m_(2))/(m_(1))`
`=(20xx100)/(50)`
`=40km//h`
`=(40xx1000)/(3600)m//s`
`=11.11m//s`
