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

b. a lightning bug, plug of grass, and a worm

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
