Answer:
v = 44,16 m/s
Explanation:
We will fixate our reference in the starting point from where Dan jumped of, at the top of the Casino. Therefore, the displacement made when dan reached the airbag would be of y= -99,4 m viewed from our reference. We describe the motion of dan with the equation:
Dan jumped from the rest, that means that the initial velocity v_0=0, therefore:
Since Dan is moving in the negative axis regarding our reference point, we take the negative root of the equation.
v_y=-√(2*(-9,81 m/s^2 )*(-99,4 m) )=44,1613 m/s
So, if we don’t take the air resistance into account, Dan would have achieved an velocity of 44,16 m/s when he reached the airbag.
I hope everything was clear with my explanation. If you need anything else, let me know. Have a great day :D
Answer:

b
Explanation:
From the question we are told that
The number of identical drippers is n = 60
The diameter of each hole in each dripper is
The diameter of the main pipe is
The speed at which the water is flowing is
Generally the amount of water used in one hour = 3600 seconds is mathematically represented as
Here A is the area of the main pipe with value
=>
=>
So
=>
=>
Generally the area of the drippers is mathematically represented as
=>
=>
Generally from continuity equation we have that
=>
=>
