1. The problem statement, all variables and given/known data A biker, who is 72.4 kg, rides down a hill at 4.76 m/s [tex][3.83^\circ[/tex] down from south], when he hits a bump which makes him go 2.00 m/s [tex][1.80^\circ[/tex] up from south]. What is the change in momentum? 2. Relevant equations [tex]p=mv[/tex] 3. The attempt at a solution Here's what I did: p=(72.4)(2.00+4.76) p=489 kg m/s I know this is probably wrong, but I didn't know how to accomodate the degrees. Can someone help me?
