Answer:
speed does water emerge from the hole v= 2.8 m/sec
Explanation:
the depth of the rectangular trough h = 0.40 m full of water
Also, given One end of the trough has a small drain plug right at the bottom edge.
we have to find the speed does water emerge from the hole.
This can be done using law of conservation of energy
the potential energy of water will be converted into kinetic energy as
⇒
h= depth, g= acceleration due to gravity and v= velocity of water from the hole
plugging the values
v= 2.8 m/sec
