Question

65) A water tank springs a leak. Find the speed of water emerging from the hole if the leak is 2.9 m below the surface of the water, which is open to the atmosphere

Answer 1

Apply the formula:

`v=\sqrt[]{2gh}`

where:

v= speed

g= gravity = 9.8 m/s^2

h= height = 2.9 m

Replacing:

`v=\sqrt[]{2\cdot9.8\cdot2.9}`

v = 7.53 m/s
