Kinetic energy is made when something is in motion. A bicycle locked to a bike rack has the least amount of kinetic energy.
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
The club was in contact with the ball for 0.013 seconds.
Why?
We can calculate for how long was the club in contact with the ball using the following equation and isolating the time from it:
From the statement we know:
- Initial speed equal to zero.
- Force equal to 272N.
- Final speed (for the moment) equal to 62 m/s.
- Mass equal to 0.058 Kg
So, substituting and calculating, we have:
Hence, we have:
Variables: Time
Equations:
Answers: The club was in contact with the ball for 0.013 seconds.
Have a nice day!
