CE BIO Maneuvering a Jet Humans lose consciousness if exposed to prolonged accelerations of more than about 7 g . This is of concern to jet fighter pilots, who may experience centripetal accelerations of this magnitude when making high-speed turns. Suppose we would like to decrease the centripetal acceleration of a jet. Rank the following changes in flight path in order of how effective they are in decreasing the centripetal acceleration, starting with the least effective A , decrease the turning radius by a factor of two; B , decrease the speed by a factor of three; or C , increase the turning radius by a factor of four.

2. An object is moving in a circular path at constant speed. If the radius of the circular path is doubled and the speed stays the same, then:
a) The acceleration decreases by four times.
b) The acceleration stays the same.
c) The acceleration is halved.
d) None of the above.

Problem 1:
During their physics field trip to the amusement park, Tyler and Maria took
a rider on the Whirligig. The Whirligig ride consists of long swings which spin
in a circle at relatively high speeds. As part of their lab, Tyler and Maria
estimate that the riders travel through a circle with a radius of 6.5 m and
make one turn every 5.8 seconds. Determine the speed of the riders on the
Whirligig.
Question 7
A roller coaster car moves on a track with one section that is a vertical circular loop
of radius R. When the car is at the top of the loop it just maintains contact with the
track. What is the car's velocity at this point?
