Momentum — practice question

A car with mass $750\,\text{kg}$ moves $400\,\text{m}$ at $25\,\text{m s}^{-1}$. It then speeds up to $35\,\text{m s}^{-1}$ and goes a further $400\,\text{m}$. What is the change in the momentum of the car due to acceleration?

  • A$7500\,\text{kg m s}^{-1}$
  • B$24\,000\,\text{kg m s}^{-1}$
  • C$45\,000\,\text{kg m s}^{-1}$
  • D$75\,000\,\text{kg m s}^{-1}$
