When do you get the greatest impulse or change in momentum?

a)When an object fully stops upon impact
b)When an object merely slows down after impact
c)When an object bounces back after impact
d)All incidents have the same impulse

It doesn't clearly say in my text material. I want to say a or d

    C)

    c is obviously the best choice. Remember, momentum is a vector, so you have to account for the signs.
