Question

(121 m/s, or 43

Answer 1

Answer:

(a) r = 328 m

(b) F = 6271.8 N

Explanation:

speed, v = 540 km/h = 150 m/s

Acceleration, a = 7 g

(a) Let the radius is r.

$a =\frac{v^{2}}{r}\\7\times 9.8 = \frac{150\times 150}{r}\\r = 328 m$

(b) The force on 80 kg pilot at the lowest point is

$F =m \times g + m\frac{v^{2}}{r}\\F = 80\times9.8 +80\times \frac{150\times 150}{328}\\\\F =784 + 5487.8 = 6271.8 N$
