You drop a stone down a well that is 9.5 m deep. how long is it before you hear the splash? the 9) speed of sound in air is 343 m/s and air resistance is negligible.

We have the following data provided to us, as we have:

Explanation:

We have the following equations in order to solve the given problem:

s=(a×t²)/2,

Rearranging all the factors in the equations we get:

t=√(2×s/a),

so,

2. Sound.

V1+V2=1,38s+0,03s=1,41s

i think its c if i'm wrong
