an object is dropped from a height of 7.00 meters and takes 1.19 seconds to fall to the ground. What is the acceleration due to gravity estimated from this measurement?
Suppose the experiment above is done five times. Determine the mean fall time and the standard error using these measuements..
Run...Time of Flight
1.....1.19s
2.....1.24s
3.....1.16s
4.....1.21s
5.....1.18s
From the results above, what is the best estimate for the acceleration of gravity?
7 = (1/2) g t^2
7 = .5 * g * 1.19^2
solve for g
