Explanation:

As w = 2000π

2πf= 2000π

f= 1000Hz

speed = wavelength × f= w/k

wavelength = 2000π/ (0.5× 1000)

= 4π

or

12.57

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
