Breaking News!!! Young pyysicist Abby from IHS has calculated her acceleration due to gravity! In a performance of three trials Abby calculated the average time in which she was in the air to calculate her maximum displacement. First: .60s Second: .65s Average time=.59s Third: .55s In order to find d, you need to use the equation d=vit+1/2at^2, already knowing you have an initial velocity of 0, an acceleration of 9.81m/s^2 and a time of .259s, because you take the average time which is .59s and divide it by two. You divide your amount of time by two, because you only want to know the time of one direction she was in the air. vi: 0 vf: d=vit+1/2at^2 d:? 0(.295)+(0.5)(9.81)(.259)^2 =.33 m a: 9.81m/s^2 t: .59s/2=.295s Abbys average vertical jump is .33 m
