1. The problem statement, all variables and given/known data 45. A freely falling object requires 1.50 s to travel the last 30.0 m before it hits the ground. From what height above the ground did it fall? 2. Relevant equations x = xi + Vit + (1/2)at2 Vf2 = Vi2 + 2ad 3. The attempt at a solution First found the initial velocity from 30.0 m left 30m = 0m + Vi (1.5 sec) + (1/2) (-9.81 m/s2) (1.5 sec)2 Vi= 27.36 m/s at 30 m away from ground Distance from original height to 30 m left (27.36 m/s)2 = (0 m/s)2 + 2 (-9.8a m/s2) d -38.15 m = d total distance = 68.15 m I hope this is right! Thank you!
