A ball with momentum of 10 kg-m/s [E] hits an object and rebounds with momentum of 6 kg-m/s [W]. What was the change in momentum?

2. Relevant equations

delta p=p(final)-p(initial)

3. The attempt at a solution

delta p=p(final)-p(initial)

delta p=(6 kg-m/s)-(10 kg-m/s)

delta p= -4 kg-m/s

This problem seems so simple, and yet it's in the middle of a worksheet full of really hard problems, so I just wanted to make sure I'm doing it right.
