A 1300 kg car is traveling along a straight road at 20 m/s. Two seconds later its speed is 24 m/s. What is the magnitude of the net force acting on the car during this time?

I don't know what equation to use, and I keep getting stuck

  • Physics - ,

    a = (Vf-Vo) / t = (24-20) / 2 = 2m/s^2.

    Fn = ma = 1300 * 2 = 2600N.

    Thank you!
