An open railroad car of mass 2500 kg is coasting with an initial speed of 14 m/s
Question:
An open railroad car of mass 2500 kg is coasting with an initial speed of 14 m/s on a friction less, horizontal track. It is raining, and water begins to accumulate in the car. After some time, it is found that the speed of the car is only 11 m/s. How much water (in kilograms) has accumulated in the car?

I am graduated in Physics in 2018, from KIRORIMAL COLLEGE, University of Delhi. Now I am persuing Master's degree in physics. I like to do physics problems. I have experience of 1 year in tutoring. I think Physics is the only subject where you understand things,how they are happening . In physics you learn Maths and apply it. So I would like to join your platform to solve many Physics problems.
