In part 1 of this lab, we will be investigating the motion of a cart as it slides down an inclined plane. Let D be the distance from the raised end to the ground and h be the vertical distance from the vertical distance from the untipped track height to the new track h eight at the raised end, as shown in the diagram below (note : the difference between this situation and the situation you will see in lab is that the end of the track will not be in contact with the ground). Also shown below is a free-body diagram showing the forces acting on the cart (neglecting friction), including the components of the gravitational force that are parallel and perpendicular to the track.

Question 1, What is the unmarked angle between F _g and its "y"component?

Question 2, What is the component of acceleration a of the cart that points along the track?

We can compute the angle e from h. sin e D'
