A man of 50 kg is standing at one end on a boat of length 25m and mass 200 kg. If he starts running and when he reaches the other end, has a velocity `2ms^(-1)` with respect to the boat. The final velocity of the boat is

A

`(2)/(3)ms^(-1)`

B

`(2)/(5)ms^(-1)`

C

`(8)/(5)ms^(-1)`

D

`(8)/(3)ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`m_(1)u_(1)+m_(2)u_(2)=m_(1)v_(1)+m_(2)v_(2)`
