Use the simulation in the interactive problem in Section 10.0 to answer the
following questions. (a) If you increase the period, will the angular velocity
increase, decrease or stay the same? (b) If you increase the period, will the
linear speed increase, decrease or stay the same? (c) If you increase the
distance from the center, will the angular velocity increase, decrease or stay the
same? (d) If you increase the distance from the center, will the linear speed
increase, decrease or stay the same?

(5.00)
Two cars are traveling around a circular track. The angle between them, from
the center of the circle, is 55° and the track has a radius of 80 m. How far apart
are the two cars, as measured around the curve of the track?
This is the end of the preview.
