1. The problem statement, all variables and given/known data Upton Chuck is riding the Giant Drop at Great America. If Upton free falls for 2.6 seconds, what will be his final velocity and how far will he fall? 2. Relevant equations 3. The attempt at a solution Finding V(final)= Vf-Vi = at ---> Vf = (-9.81)(2.6) = 25.5 The second part is a little confusing. Why don't these equations come out with the same answer? Vf^2 = Vi^2+2a(DeltaX)...Rearranged to... -DeltaX = 0 + 2(9.81) - 25^2 = 650meters something which doesn't really make sense. The other I used was X= 1/2at^2 = 33meters The second is the correct answer but why didn't the equation I do work? Since we know the initial is 0, the final is 25.5. We also know the time.
