A frog falls from a rainforest tree. If we ignore wind resistance how long does it take the frog to fall from a distance of 12 meters?

free fall (cuz we are ignoring the wind resistance )
summation of forces = m * a
m*g = m * a (weight is the only acting force during free fall)
=> a = 9.8
x = 0.5 * a * t^2... solve for t
t = 1.564 sec
