A shortsighted sheriff fires at a cattle rustler with his trusty six-shooter. Luckily for the rustler, the bullet misses him and goes in the town water tank, causing a leak.
The top of tank is open to the atmosphere.
Assume that the water strikes the ground 4.25 m from the hole in the tank. When the hole is 2.45 m above the ground, determine how far above the hole is the water level?
