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
The coefficient of kinetic friction ∝=9.81
Given that mass of block is 80kg .
Pulleys and ropes are massless and frictionless.
Coefficient of kinetic friction ∝ means the ratio of kinetic friction force of contacting surfaces to normal force .
Being a ratio parameter its unitless parameter.
from these equations
Since there is no involvement of tension, g=∝
∝=9.81
