Question

Apilot of mass 70 kg rides a fighter jet The fighter jet moves in a vertical circle of radius 100 m at a constant
‘speed of 120 mis. Determine the force exerted by the seat on the pilot at the top of the circle (note that the pilot is fastened
to the seat)

Answer 1

Answer:

the  force exerted by the seat on the pilot is 10766.7 N

Explanation:

The computation of the force exerted by the seat on the pilot is as follows:

$F = Mg + \frac{MV^2}{R}\\\\= 70 \times 9.81 + \frac{70 \times 120^2}{100}\\\\= 10766.7 N$

Hence, the  force exerted by the seat on the pilot is 10766.7 N
