[SOLVED] (101)Acceleration due to gravity Ok, this should be really strait forward. Its only problem C that I am not getting correct. 1. The problem statement, all variables and given/known data An object is observed to fall from a bridge, striking the water below 3.36 s later. (a) With what speed did it strike the water? (b) What was the average speed during the fall? (c) How high is the bridge? 2. Relevant equations a) 9.8*3.36 = 32.928 m/s - correct b) Vi+Vf/2 = 16.464 m/s - correct c) ? 3. The attempt at a solution Ok, acc due to gravity = 9.80m/s^2 So, in the first second, the object fell 9.8m. In the second second, it fell 19.6m. t=3 it fell 29.4m. t=3.36 it fell 32.928m. Adding all of these would give me the total distance fallen (height of the bridge). The answer 91.728m is incorrect. Am I attacking this the wrong way? Thank you!
