Given,
The mass of the car, m=1200 kg
The velocity of the car, v=25 m/s
The momentum is the product of the mass and the velocity.
Therefore the momentum of the car can be calculated as,
[tex]p=mv[/tex]On substituting the known values,
[tex]p=1200\times25=30000\text{ kg}\cdot\frac{m}{s}[/tex]Therefore the momentum of the car is 30000 kg·m/s
