Answer :
Final answer:
The centripetal acceleration of a small plane when it completes a circle with a radius of 4000 meters can be calculated using the formula ac = v² / r, where ac is the centripetal acceleration, v is the velocity, and r is the radius.
Explanation:
The centripetal acceleration of a small plane when it completes a circle with a radius of 4000 meters can be calculated using the formula:
ac = v² / r
where ac is the centripetal acceleration, v is the velocity, and r is the radius.
Since the radius is given as 4000 meters, we need to know the velocity of the plane to calculate the centripetal acceleration.
