A car travels in a circle whose radius is 31 m, with a speed of 19 m/s.
(1) What is the magnitude of the car's acceleration?
(2) What is the nature (origin) of the horizontal force on the car? (What is exerting the force?)
The force causing the car to turn is:
a) the Coriolis force from the car's non-inertial
b) the force of friction between the car's tires and
c) the gravitational force between the earth and the
d) the mechanical force provided by the car's
