Answer» s = U t + 1/2 G t^2s is the height above GROUND, 300 m.u is initial vertical VELOCITY, zero.t is time to reach the ground.g is ACCELERATION of gravity near Earth, 9.8 m/s^2.300 m = 0 t + 1/2 (9.8 m/s^2) t^2300 m = (4.9 m/s^2) t^261.22 s^2 = t^27.82 secondsExplanation:Hope this will help you |
