**bobpursley**, Sunday, September 16, 2012 at 10:07pmthe height is the same, as is the time (one is 1.25 seconds longer)

happle=1/2 g t^2

horante=-28*(t-1.25)+1/2 g (t-1.25)^2

solve for t in the first equation

t=sqrt(2h/g)

put that t into the second equation

h=-28(sqrt(2h/g) - 1.25)-4.9(sqrt (2h/g)-1.25)^2

expand this out, the height h divides out, solve for t. Then, calculate h.
