Kent's ball will go in the direction that the ball is going right when he lets go of it.
Imagine this like an analog clock. 12 is forwards, 6 is behind, 3 is right, and 9 is left relative to Kent. If Kent is twirling the ball clockwise and lets go at 3, the, the ball will go behind him as the velocity vector exactly at 3 points behind Kent in a clockwise motion. Here are Kents velocity vectors according to my clock analogy. Hope this helps because this is how I learned it!

Answer:
n=770,880.
Explanation:
Given that
P= 2200 MW
Power of wind farm = 0.4 or 40%
So the power produce by wind farm = 0.4 x P
P'=0.4 x 2200 MW
P'=880 MW
P'=880,000 KW
We know that
1 year = 365 days
1 day = 24 hr
So
1 year = 365 x 24 hr
1 year = 8760
So the energy produce in one year
E= 8760 x P'
E= 8760 x 880,000 KW
Given that average house hold use 10,000 KW-hr
So lets take total n number of house hold use power
E= n x 10,1000
n=770,880.
