Applying Newton's Second Law - Conceptual Example 5.6-3

 

A ball is shot at high speed into a frictionless channel that is in the shape of a segment of a circle with center at O. The channel is frictionless and sits on a horizontal table top. The figure shown is the top view.

 

 

Which of the following force(s) are acting on the ball when it is within the frictionless channel at position B?

Check all that apply.

 

A downward force of gravity.
A force pointing from O to B.
A force in the direction of motion.
A force pointing from B to O.

 

 

 

 

Which path would the ball most closely follow after it exits the channel at C and moves across the frictionless table top?
