A car is driven into a sharp bend in a horizontal road. The radius of the bend is 
, and the coefficient of friction between the tires and the ground is 
.
Driving a car in a bend .
Draw the external forces on the car and name them.
What does the maximum speed of a car depend on when driving safely through a bend in a horizontal road?
What is the maximum speed with which the car can drive safely around the bend?
On normal road traffic, only the right half of the road should be used. Based on the equation obtained in part b above, explain on which side of the bend the car can drive at a higher speed.
of the car and
with which the ground acts on the car.
and the radius 
of the bend as shown by the equation below:
.
