Standing beside a well in the mines of Moria, Peregrin "Pippin" Took tosses a pebble upward at 2.53 m/s from an initial height of 1.82 m above the ground. After being tossed into the air, the pebble goes up, reaches its zenith, then comes back down to fall into the well. Pippin hears the pebble splashing into the water below 2.09 s after tossing it. Assuming that sound travels practically instantaneously through the air, how far below the surface (in meters) is the water in the well?
