Answer:
Mass of the car is 1576 kg.
Explanation:
Let the mass of the car be kg.
Given:
Initial velocity of the car is,
As the car stops, final velocity of the car is,
Change in momentum is,
Now, we know that, momentum is given as the product of mass and velocity.
So, change in momentum is given as:
Therefore, the mass of the car is 1576 kg.
