A stunt pilot in an air show performs a loop-the-loop in a vertical circle of radius 3.80* 10^3 m. During this performance the pilot whose weight is 644 N, maintains a constant speed of 2.05 *10^2 m/s.
(a) When the pilot is at the highest point of the loop determine his apparent weight in N.
(b) At what speed, in m/s, will the pilot experience weightlessness?
(c) When the pilot is at the lowest point of the loop determine his apparent weight in N. N
Solutions
Expert Solution
(a) When the pilot is at the highest point of the loop determine his apparent weight in N.
At the height point of the loop, centripetal force will be acting upwards, the weight of the pilot will be acting downwards
Apparent weight,

(a) ANSWER: 
==========================
(b) At what speed, in m/s, will the pilot experience weightlessness?
The pilot will experience weightlessness when the apparent weight is zero
Apparent weight, 
(b) ANSWER: 
============================
(c) When the pilot is at the lowest point of the loop determine his apparent weight in N. N
At the lowest point of the loop, centripetal force and weight of the pilot will be acting downwards.

The pilot of an airplane executes a loop-the-loop maneuver in a
vertical circle. The speed of the airplane is 305 mi/h, at the top
of the loop and 450 mi/h at the bottom, and the radius of the
circle is 1 180 ft. Note: His apparent weight is equal to
the magnitude of the force exerted by the seat on his body. (a)

Will Rogers spun a lasso in a vertical circle. The diameter of
the loop was 6 ft, and the loop spun 50 times each minutes. If the
lowest point on the rope was 6 inches above the ground, write an
equation to describe the height of this point above the ground
after t seconds.
Please write nicely.

A box with mass 0.0325 kg moves in a vertical circle that has a
radius of 0.600 m on the inside of a circular track. When the box
is at the bottom of its path, point A, the magnitude of the normal
force exerted on the box by the track has magnitude 3.75 N. When
the box reaches the top of its path, point B, the magnitude of the
normal force exerted on the box has magnitude 0.665 N.

7. The University Skydiving Club has asked you to plan a stunt
for an air show. In this stunt, two skydivers will step out of
opposite sides of a stationary hotair balloon 1500 meters above the
ground. The second skydiver will leave the balloon 20 seconds after
the first skydiver but you want them both to land on the ground at
the same time. The show is planned for a day with no wind so assume
that all motion isvertical....
