    In a collision between two unequal masses, how does the impulse imparted to the smaller mass by the larger mass compare with the impulse imparted to the larger mass by the smaller one?

    A) It is smaller.
    B) The answer depends on how fast they are moving.
    C) They are equal.
    D) It is larger.

    3. The attempt at a solution

    Impulse is the force multiplied by the time for which that force acts.
    In this case, what can you say about the force of object 1 on 2 and object 2 on 1?
    What can you say about the time for which these 2 forces act?

    In conclusion, what can you say about the 2 impulses?

    The force is the same and the time in the same; therefore, the impulse on each object is the same.
