Answer:

Step-by-step explanation:
Given that,
Mass of the car,

Initial speed of the car,

Final speed of the car,

To find,
The maximum mass of grain that it can accept.
Solution,
We know that according to the law of conservation of momentum, the initial momentum is equal to the final momentum.




Therefore, the maximum mass of grain that it can accept is 2554.83 kg. Hence, this is the required solution.
