    speed of sound and g are rouded up to 340 and 10.0 respectively 1/2*g*t^2 = Vs(1.5-t) 5.0t^2 = 340*1.5-340t t = (340-√340^2+20*510)/-10= 1.468 sec h = 340*(1.5- 1.468) ≈ 10.8 m

    Neglect the speed of sound in this experiment. s = ut + 0.5 at² where u = 0. s = 0.5 * 9.8 * (1.5)² = 11.025 meters. This answer should suffice and may be rounded off to 11 meters.
