If you throw a ball against a wall, which of the three impulses is the greatest: throw, bounce, or catch?

I think it would be the bounce because the momentum of the ball is highest when it hits the wall. and basically impulse is the change in momentum...am i correct ???.....if not then wat else is possible...

• physics -

bounce:
Δp =p2 –p1 =m•v2- (-m•v1) = m(v1+v2)

• physics -

thank you for the help ...........but how is the (m.V1) negative ???
