Question

(a) What is the apparent weight of the pilot at the highest point in his trajectory?

N

(b) What is the apparent weight of the pilot at the bottom of his trajectory?

N

(c) At what speed will she experience weightlessness?

v =  m/s

A 608-N stunt pilot maintains a constant tangential speed
of 215 m/s while performing a vertical loop-the-loop
of radius 2.85 km as shown in the figure.

Weight vs. Perceived Weight
You may recall that the force we perceive to be
our weight is not our actual weight. The force that our
senses experience as weight is the contact force exerted on us
by whatever happens to be supporting some or all of our weight.

This perceived weight is referred to as "apparent weight."

Explanation / Answer

part a)

at top pilot will feel weightless

0

part b)

at bottome pilot will feel

N = mg + mv^2/r

N = 608 + 62.04 * (215)^2 / (2.85 x 10^3)

N = 1614.25 N

part c )

at top = F =mg = ma = mv^2/r

v = sqrt(rg)

v = 1608.66 m/s
