A trolley containing water has total mass `1000 kg`. Now water starts coming out of the trolley at the rate of `10 kg//s` from below it. Find the velocity of the trolley after 50 sec, If the initial speed is `10 m//s` on the horizontal frictionless road.

A

`10m//s`

B

`20 m//s`

C

`15m//s`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
The velocity of system will not change in horizontal direction as water is leaking out vertically down. Because leaking water does not exchange any momentum with trolley in horizontal direction.
