The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal tabletop. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r."
Consider the following distinct forces:
A downward force of gravity.
A force exerted by the channel pointing from q to O.
A force in the direction of motion.
A force pointing from O to q.
Which of the above forces is (are) acting on the ball when it is within the frictionless
channel at position "q"?

An automobile moves on a level horizontal road in a circle of radius 50 m. The coefficient of static friction between tires and road is 0.50.
(a) Calculate the maximum speed with which this car can round this curve. Now, suppose the road is covered with ice, there is no friction. Instead, the road is banked.
(b) Calculate the angle the road must be banked at in order to make the car round the curve with the same maximum speed.
