A car weighing 15,000 N is speeding down the highway at 90 km/h. What is its momentum?

  • physical science -

    Convert the weight W (in N) to the mass M (in kg).

    M = W/g

    Then convert the speed in km/h to m/s.

    V = 90 km/h = 25 m/s

    The momentum is M*V. The preferred units are km*m/s.
