1. The problem statement, all variables and given/known data 2. Relevant equations KE = 1/2 M V2 P = M V 3. The attempt at a solution p = mv pcardinal = .0450vcardinal pbaseball= .144vbaseball 0450vcardinal/144vbaseball Why is this not the correct answer? I know KE are equal so KEcardinal= ½ .0450 v2 KEbaseball= ½ .144 v2 so .0450 v2 = .144 v2 how is knowing the KE are equal any helpful, and why is my original answer not right?
