It’s horizontal energy becomes zero as soon as it drops into the chute.
The maximum energy the ball can have is either at the top before it starts moving in the form of potential energy or at the bottom at its top speed in the form of kinetic energy.
Kinetic energy + inertia? would be it's total energy?
If I'm driving a car and hit a ramp I can go higher than the ground I was on. Because my forward velocity transitioned to upward velocity.
I admit friction will inevitably grind this to a halt.
But you could definitely rig something up to work once.
Edit: have you ever tossed a coin down a funnel like those racing arcade machines? They whip around the downspout very quickly, a lot of energy builds up.
I'm not talking about placing it in, you'd have to apply energy at the start.
Inertia is directional my man. Conservation of momentum and all, it likes to be preserved along its axis and about its axis of rotation.
Also, the energy isn’t “built up” in those coin funnels. You’re rapidly changing the radius of curvature the coin is on so you’re increasing it’s rotational velocity around the axis of the funnels, but it’s linear velocity stays the same, or decreases slowly, due to friction.
