Question

An airplane flying at $100m/sec$ dives in a vertical plane along the circle of radius $200m.$ The mass of the pilot is $75kg$ What will be the force exerted by the pilot on his seat when the airplane is at the maximum height?

• A. $\text{300 kg wt}$
• B. $\text{200 kg wt}$
• C. $\text{450 kg wt}$
• D. $\text{100 kg wt}$

Answer 1

The correct option is A $\text{300 kg wt}$

At the top of the circle

$F_c=T+mg$

$\frac{m{v}^2}{r}=T+mg$

By substituting the values in the equation we get

$T=300kg-wt$

Hence the maximum force exerted by the pilot at maximum height is$300kgwt$
