A stone is released from rest from the edge of a well at time t0 = 0 s. When it hits the bottom, a sound wave is generated. You can think of the sound wave as an object traveling from the bottom of the well towards the surface at a constant velocity vs = 340 m/s. At time t = 2.6 s, the sound of the stone reaches the top of the well.
Question #1: How deep is the well?
Question #2: At what time did the rock touch the bottom. Use 9.8 m/s2.
Hint: Use a symbol (e.g., t1) to label the time at which the sound wave is generated and starts moving.
Hint: You will get two solutions for depth. How can you check which is the correct one?
