2atest pilot wcighing 85 kg is strapped into a large centrifuge machine for training the machine
spins rapidly to simulare increased gravitational forces on the body
a the machine spins the pilot in a cirde with a 9.9 m radius, what should be the period of
folation so that the pilot experiences a force equal to twice his body weight? what should be
the period of rotation so that the pilot experiences a force equal to three times his body
weight
b. astationary observer watches as the pilot spins in the machine. from the frame of reference of
the stationary observer, how fast is the pilot traveling as he passes by while experiencing a force
three times that of gravity? give your answer in revolutions per minute, ipm
c. if the radius of the cirde increases but the pilot continues to spin at the same speed, does the
pilot experience more or less force? what can be done to maintain the same force on the pilot?

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

because growing process had stoped after 4-5 year

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
