radius 200 m is raised to make an angle of 150
with the horizontal.
a) Which force provides the necessary
centric petal force for a car taking the circular
track?
b) Name the process by which the outer
side of a curved track is raised a little above
the inner side.
c) Using the data provided in this case,
determine the maximum permissible speed to
