Answer to Question #17520 in Mechanics | Relativity for Haley D
height of 2.2 m How far from the point of the drop will the rock hit the ground?The acceleration of
gravity is 9.8 m/s2
H = gT²/2 ==> T = √(2H/g) = √(2*2.2[m]/9.8[m/s²]) ≈ 0.45 [s].
So, a rock will drop
D = 0.45[s]*44[m/s] = 19.8 meters
far from the point of the drop.
