A. If Force = pain, which will hurt more, moving INTO the balloon, or moving AWAY from the balloon right as it hits me?  Why?     B. My head has a mass of 4.5 kg.  If the balloon (hits and) sticks to me, how fast will my head (and the balloon) be travelling after I get hit?     C. How much impulse does the balloon experience? (Don’t forget units!)   D. The balloon deforms, then pops, taking a total of {0.18} seconds of impact.  How
