1. The problem statement, all variables and given/known data Figure out the height of the building using free fall formulas and only knowing two times: 3.25 second acceleration, 1.25 seconds decceleration. Find the height. 2. Relevant equations Dy=V0t + 1/2at2 (only one I can think of that applies) 3. The attempt at a solution Dy=V0t + 1/2at2 V0t=0 Dy= 1/2at2 Dy= .5(9.8m/s2)(10.5625) Dy= 51.8 m I am really stumped on this for some reason! I'm not even sure if I am using the correct formula. Any and all help is appreciated! Thanks y'all!!!
