You throw a coin into a well, 1.5 seconds later you hear a splash
the acceleratoin is g, 9.81 m/s², the beginnig speed is 0
Homework Equations
x= x0 + v0t + (at²)/2
The Attempt at a Solution
x= 0+0+ (9.81*1.5²)/2
x= 11.04 m
Yet this is not the sulotion.
I think I have to use the speed of sound into the equation (340m/s right?), however I have no idea where I have to do this...
