1)
Computer-controlled display screens provide drivers in the Indianapolis 500 with a variety of
information about how their cars are performing. For instance, as a car is going through a turn,
a speed of 221 mi/h (98.8 m/s) and centripetal acceleration of 3.00 g (three times the
acceleration due to gravity) are displayed. Determine the radius of the turn (in meters).

A centrifuge is a device in which a small container of material is rotated at a high speed on a
circular path. Such a device is used in medical laboratories, for instance, to cause the denser
red blood cells to settle through the less dense blood serum and collect at the bottom of the
container. Suppose the centripetal acceleration of the sample is 6.25x103 times as large as
the acceleration due to gravity. Determine how many revolutions per minute is the sample
making, if it is located at a radius of 5.00 cm from the axis of rotation?
