An open railroad car of mass 2449 kg is coasting with an initial speed of 17 m/s on a frictionless, 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 10 m/s. How much water (in kilograms) has accumulated in the car?
