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

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!

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
