Answer:
The apparent weight is 5 times greater than the original weight at the bottom.
Explanation:
Given:
Mass of the pilot, m = 84 kg
Velocity of the jet, v = 345 m/s
Radius of the loop, R = 3.033 km = 3.033 * 10^3 m
We have to find the apparent weight that the pilot feels.
Let the apparent weight be "N" .
Apparent weight :
- It is based on where is the position of the pilot in the loop-the-loop.
- The apparent weight is the highest at the bottom of the loop-the-loop.
- Because the weight acts down and the normal force acts towards the center of the circle.
From the FBD shown we can say that :
apparent weight (N)

⇒
Therefore,
The force exerted by the seat on the pilot at the bottom of the loop is greater than the pilots weight by a factor of 5.
