A car tows a trailer which has a mass of 182kg. The car starts from rest on a horizontal road with an acceleration of 2.40m/s^2. As soon as the trailer starts to move a friction force of 64.0N acts on the trailer. Calculate the force which the car exerts on the trailer.

  1. horizontal force = Tow force - friction force = m a
    Tow force - 64 = 182 * 2.40
