## Homework Statement

(see attachment for image)

A steel ball is released from a ramp and enters at the position marked.

Draw and explain the paths taken by both balls

(explain the difference between the paths)

## Homework Equations

## The Attempt at a Solution

So the smaller ball follows a path with a smaller radius than the larger curve

the larger ball is moving faster BUT how does this explain why the curve is greater (mv

^{2}/r is the force needed for the steel ball to move in a circle BUT there surely are not any extra forces supplying the required centripetal acceleration). I would have presumed that frictional forces don't really change as the steel ball is smooth?
