Consider two frictionless inclined planes with the same vertical height. Plane 1 makes an angle of 30.0 with the horizontal, and plane 2 makes an angle of 70.0 with the horizontal. Mass 1 is placed at the top of plane 1, and mass 2 is placed at the top of plane 2. Both masses are released at the same time.
At the bottom, which mass is going faster?
