A et traveling at speed of 2.20 x 102 m/s executes vertical loop th a radius of 4.25 x 102 m.(see Figurn (h).) Find the magnitude f the force nf the sear nn70.0 kg pilot t the following positions. a) the top of the loop (b) the tottorm of the loop

Explanation / Answer

Given that,

v = 2.2*10^2 m/s

R = 4.25*10^2 m

m = 70 kg

(a)

Magnitude of the force top of the loop,

Ft = mv^2 / R - mg

Ft = (70*(2.2*10^2)^2 / 4.25*10^2) - (70*9.8)

Ft = 7285.76 N

(b)

Magnitude of force at bottom of the loop,

Fb = mv^2 / R + mg

Fb = 8657.76 N
