I mean if he flies 5g that means that's his average speed too
The question ask to find and calculate the induced current in the loop as a function time and the best answer would be that the induced current in the loop is 0.08 amperes. I hope you are satisfied with my answer and feel free to ask for more if you have clarifications and further questions
Answer:
The velocity is 
Explanation:
From the question we are told that
The initial speed is 
The cross -sectional area of the first pipe is 
The cross -sectional area of the second pipe is 
Generally from continuity equation we have that

So

=> 
=> 
A
The horizontal force cancels out. The two 4Ns go in opposite directions. So they don't affect the outcome.
The Vertical force is 6N up - 2 N down = 4 N Up
Answer 4 N up
B
The horizontal and vertical forces cancel out. Each gives 3N - 3N =0
The net force is 0
C
You only have horizontal forces on this one
5N - 3N = 2N
The answer is 2N to the right.
