A tank is filled with water to a height H. A hole is punched in the wall at a depth h below the water surface. Find the distance x from the wall at which the stream strikes the floor. Could a hole be punched at another depth so that this second stream would have the same range? If so at what depth? For what value of h is range maximum?

Options

A. `x=2[D(H-D)]^(1//2)`
B. `x=2(gD)^(1//2)`
C. `x=2[D(H+D)]^(1//2)`
D. None of these

Answer

A
