Suppose that after a number of measurements, you were to find an average time δt=(0.0031±0.0002) s using a gate separation δd=(1.0±.1) cm when dropping a ball from the height h=(0.510±0.002) m. calculate g. give your answer in units of m/s2 to three digits (even though they may not all end up being i dont know what a gate seperation is. when i use a=(2h)/(t^2) to calculate g i get 106555.6712 and thats way too big. how do i work the gate seperation into it to get g i know how to do the uncertainty part.
