ANSWERS
This is simple, during the very moment where the cart is momentarily frozen above the peak, the potential energy is at the highest level (Potential 100, Kinetic 0) because is stored in the cart and it is not moving for a fraction of second, and then when the cart starts to move down the slope kinetic energy (Potential 0, Kinetic 100) is now at the highest level because it is moving and in motion.
At the last peak, there are some potential energy, because the cart is barely frozen and still moving a little bit, that's why there is also a kinetic energy right there (Kinetic 75, Potential 25).
THINGS TO REMEMBER
POTENTIAL ENERGY (STORED ENERGY)
• When object is at rest, momentarily frozen, immobile, stationary and unmoving.
KINETIC ENERGY (ENERGY IN MOTION)
• When object is accelerating, moving, or in motion.
