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

c) up is the direction the magnetic force is acting on the charge.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
