1. The problem statement, all variables and given/known data Lindsay was on her way to visit her grandmother in Kansas when suddenly a tornado picked her up and transported her to Oz. While standing beside a 198m cliff, she dropped a yellow brick over the side. It has a mass of 1.9Kg. As it was plummeting to the ground, she decided to time the last 50m of its fall. She measured 1.5s on her stop watch. She later impressed the wizard by correctly calculating the gravitational acceleration constant of Oz. What was it? 2. Relevant equations d = V1t + 0.5(a)(t)^2 d = V2t - 0.5(a)(t)^2 d[total] = 198m d[timed] = 50m m[timed] = 1.9Kg t = 1.5s 3. The attempt at a solution I tried to use all the equations I know, but I'm always missing one variable to complete it. Could you guys help me out and give me a starting point so I can finish it? Greatly appreciated.
