During a collision that last 3 seconds, an object has its momentum changed by 3 kgm/s. What was the average Force acting on the object (in Newtons) during this collision


  1. Answer:

    F = 1 N



    Change in momentum = 3 kg m/s

    time, t = 3 s

    Force = ?

    We know,

    Force is equal to change in momentum per unit time.

    F = \dfrac{\Delta P}{t}

    F = \dfrac{3}{3}

    F = 1 N

    Hence, average force acting on the object during collision is equal to 1 N.
