3)A modern "Top Alcohol" dragster can finish an (approximately) 400 m race at a speed of 120" A modern "Top Fuel" dragster can finish an (approximately) 300 m race at a speed of 160". a) What constant acceleration is necessary to achieve this? You're given a distance and initial/final speeds, and asked for acceleration, so the form you want is: 2aA.c = A (v2) For the faster one on the shorter track, the answer I got was 43"}, and for the other, 18 b) Express that acceleration as a multiple of "g." One or two significant figures at most is fine. All this is asking you to do is to divide your answer to the previous part by ten... c) The web page for governing body for the sport (the NHRA) claims these cars "launch from 3 g from a standing start.” (5gs for versions B & D.) (That is, experience three times the acceleration due to gravity, "g.") Is this consistent with your answer to the last part, and if not, what might simply explain a significant difference? It's not really quite consistent, but we assumed constant acceleration, and that is not what one would expect. TE Za fom
