A car drives at a constant speed around a
banked circular track with a diameter of 127 m. The motion of the car can be
described in a coordinate system with its origin at the center of the circle.
At a particular instant the car’s acceleration in the horizontal plane is given
by

(a) What is the car’s speed? (b) Where (*
