Homework Statement
A water balloon takes .22 s to cross the 130 cm high window, from what height above the top of the window was it dropped?
The Attempt at a Solution
I'm using:
v^2 = vo^2 + 2a(x - xo)
v = distance/time
v = 1.30 m / .22 s = 5.91 m/s
(5.91 m/s)^2 = 0 + 2(9.8 m/s^2)(x)
x = 1.78 m from release to bottom of window
1.78 m - 1.3 m = distance of release from top of window
.48 m
I'm doing something wrong since the available answers aren't .48m...and it is something simple.
