Pulling out of a dive, the pilot of an airplane guides his plane into a vertical circle. At the bottom of the dive, the speed of the airplane is 320 m/s. What is the smallest radius allowable for the vertical circle if the pilot's apparent weight is not to exceed 7.0 times his true weight

1.74 km

Explanation:

We are given that

Speed of airplane,v=320 m/s

We have to find the smallest radius allowable for the vertical circle if the pilot's apparent weight is not exceed 7.0 times his true weight.

Let true weight =w

Apparent weight=7w

According to question

We know that

Where

Where 1 km=1000 m

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
