Jerry measures the time it took for a ball dropped from a balcony to hit the ground. His stopwatch reads 2.3 seconds. How high is the balcony?
A. 52 m
B. 11 m
C. 9.5 m
D 26 m

Respuesta :

I also have this question and i think the answer is D.

I used the formula X=Xo+VoT+1/2AT^2

We are looking for the distance and know the time (2.3s)

X=0+0(2.3s)+.5(9.8)(2.3s)^2

9.8 is earths gravitational acceleration

and if you put it all together you should get 25.921

rounding it to 26. Please let me know if im wrong!
