A truck is moving on a frictionless surface with uniform velocity of 10 
. A leak occurs in the water tank of the truck at the rate of 2 
What is the speed of truck after 50 
, if the mass of truck is 100 kg and mass of water in the truck initially was 100 
?
Text Solution
Verified by ExpertsA
The combined mass of the system 
The velocity of the truck, 
The rate at which the water leaks, 
Step 2 . Find the velocity:
Water lost in 50 s is given by 
The final mass of the system is 
Assume the final velocity of the truck as 
Now, from the conservation of linear momentum we have
