Water drips from the nozzle of a shower onto the floor 200cm below. The drops fall at regular equal intervals of time, the first drop striking the floor at the instant the fourth begins to fall. Find the locations of the second and third drops when the first strikes the floor.(adsbygoogle = window.adsbygoogle || []).push({});

First I found the total time it takes for 1 drop to hit the bottom of the floor with equation (1): [tex]y-y_0=v_0t-\frac 1 2 gt^2[/tex]

[tex]\Delta y =-200cm[/tex]

[tex]v_0=0m/s[/tex]

Solved for t: [tex]t=\sqrt \frac{-2y}{g}=\sqrt \frac{-2 \times -0.200m}{9.81 m/s}}\approx .202s[/tex]

From there, I split the time into 4 equal intervals, and used those times I got and plugged it back into equation (1). But this method isn't correct, so I'm not sure where to go from here.
