A pilot, whose mass is 84.0 kg, makes a loop-the-loop in a fast jet. Assume that the jet maintains a constant speed of 345 m/s and that the radius of the loop-the-loop is 3.033 km. What is the apparent weight that the pilot feels (i. e., the force with which the pilot presses against the seat) at the bottom of the loop-the-loop?

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 :

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.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
