An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0 kg pilot does not want the centripetal acceleration to exceed 7.00 times free-fall acceleration.

The force will be "5,488". A further solution is provided below.

Explanation:

The given values are:

speed,

v = 100m/s

mass,

m = 80 kg

acceleration,

a = 7

Now,

Radius will be:

⇒

⇒    

⇒    

⇒    

Force will be:

⇒

⇒    

⇒    

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

object 2 because all the other ones are wrong
