A car with a mass of 1400 kg is traveling at a speed of 40 ms. What is its momentum?

Momentum is calculated using the formula ( p = mv ), where ( p ) is momentum, ( m ) is mass, and ( v ) is velocity. For a car with a mass of 1400 kg traveling at a speed of 40 m/s, the momentum would be ( p = 1400 , \text{kg} \times 40 , \text{m/s} = 56,000 , \text{kg m/s} ). Thus, the car's momentum is 56,000 kg m/s.
