Question
Suppose you throw the stone downward into the well with a speed of $2.1 \mathrm{~m} / \mathrm{s}$. How long does it take before you hear the splash?
Step 1
First, we need to find the time it takes for the stone to reach the water. We can use the equation of motion: h = vi*t + 0.5*a*t^2 where h is the depth of the well (20 m), vi is the initial velocity (2.1 m/s), a is the acceleration due to gravity (9.81 Show more…

You drop a stone from rest into a well that is 7.35 m deep. How much time elapses before you hear the splash?
A rock is thrown downward into a well that is 8.42 m deep. If the splash is heard 1.07 seconds later, what was the initial speed of the rock? Take the speed in the air to be 343 m/s.
