Ball rolling on incline

How fast does a ball have to be traveling at the edge of a ramp in order to not re-contact the corner of the ramp? In terms of ball radius r, gravitational acceleration g, incline angle [math]theta[/math], what is the minimal speed v that the ball must have at the edge of the ramp? Adjust the parameter sliders. Either drag the time t slider or press the animate button. Checking the "set vmin" checkbox will set the speed to the minimum value required to not re-contact the corner. Unchecking the box will allow you to see the trajectory for speed values of your choosing.
