Question

A truck is moving on a frictions are
velocity of 10 m/s. A leak occurs the n the water tank of the
truck at the rate of 2 kg/s. What is the speed of truck
50s if the mass of truck is 100 kg and mass of water in the truck initially was 100​

Answer 1

Answer:

Explanation:

After 50s the mass of the truck becomes 100kg because after 50s, the mass lost as water is 50(2)=100kg, I.e all water is lost from the truck.

Conserving momentum:

200(10)=100v

Therefore v=20m/s

Hope this answer helped you

Answer 2

Answer:

10 m/s

Explanation:

As we know if we throw anything from a body in motion it will gain it's velocity so water leaking out will also have velocity of 10m/s so there will not be any change in velocity of truck
