Consider two frictionless inclined planes with the same vertical height. Plane 1 makes an angle of 25.0 degree with the horizontal, and plane 2 makes an angle of 55.0 degree with the horizontal. Mass m_1 is placed at the top of plane 1, and mass m_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?
C. Neither; they both have the same speed at the bottom.
They both lose the same amount of gpe.
