The glass is falling at
The glass is falling at constant gravitational acceleration. From the formula s = vot + ½gt2; vo = 0 and g = 9.81 m/s2. Solving for t:
$t = \sqrt{\dfrac{2h}{g}}$
The sound is moving at constant velocity. From the formula s = vt, s = h and v = 340 m/s. Solving for t:
$t = \dfrac{h}{340}$
tglass + tsound = 3 seconds
$\sqrt{\dfrac{2h}{g}} + \dfrac{h}{340} = 3$
$h = 40.69 ~ \text{m}$
Thank you very much sir! This
Thank you very much sir! This will definitely help a lot in my review.
