Energy storage: Spring to gravitational field

Data collection

Each video shows the launch of the cart with 4-5 different system masses. For each video, record the following:

• The slope of the ramp.
• The mass of the cart and the mass added on top of it.
• The initial position of the cart.
• The position of the cart when it comes to a stop (the highest it gets).

Videos

• 3° ramp (problems with this video, use the other three instead).
• 7° ramp
• 10° ramp
• 13° ramp
