Storm Runner:

Mass of Car = 8255 kg Average weight of each Person = 150 lbs = 68.18 kg 68.18 (20 people per car) + 8255 = 9618.6 kg Height= 5 meters

U= mgh U= (9618.6)(9.8)(5) U= 471311 J

KE= 1/2mv² KE=(1/2)(9618.6)(6.176)² KE=183441 J

v= slope of position graph v= 6.176 m/s

a= slope of velocity graph a= 8.787 m/s/s

W= Fd=(ma)(d) W=(9618.6)(8.787)(5) W=422593 J

P= mv P= (9618.6)(6.176) P= 59404.5 (kg x m)/s

Great Bear: mass of car=9071.85 m=68.18(20)+9071.85=10435.5 height=3 meters

v=9.463 a=10.91

U=mgh U=(10435.5)(9.8)(3) U=306804 J

KE=1/2mv^2 KE=1/2(10435.5)(9.463)^2 KE=467241 J

W=(ma)(d) W=(10435.5)(10.91)(5) W=569257 J

P=mv P=(10435.5)(9.463) P=98751.1 (kg x m)/s

Assumptions: I assumed that the stormrunner was about the same mass as the sidewinder. I also estimated there to be about 20 people in each ride. Finally, I estimated the height and distance for each ride.

All of my results seem to be reasonable.
