1. The problem statement, all variables and given/known data On an alien planet you throw a stone upward and measure the times Ta and Tb. The difference in heights of point a and point b is h. Calculate the acceleration due to gravity. Ta = 7.1s; Tb= 4.4s; h = 15.1m 2. Relevant equations a = dv/st v(t) = vo - gt 3. The attempt at a solution I have tried solving a = t*(2gh)^.5. I have also tried a = 2h/(Ta-Tb). I keep getting numbers that are far too great I believe based off of the numbers I am given.
