The following is a simulation for a real physics demonstration. A ball is placed in the funnel and the funnel cocked by compressing a spring. The track is raised at one end so that when it is released the cart accelerates down the track. At a certain point a bump below the track trips a lever, releasing the spring and ejecting the ball perpendicular to the track. Where will the ball fall? * (a) The ball will fall in front of the funnel. * (b) The ball will fall behind the funnel. * (c) The ball will fall IN the funnel. [b:601ec2c994]You can drag the left slider to change the angle of the track.
