    I Distance traveled by a ball down a ramp and on a flat path

    Look forward to that insight, but if you say infinitely greater normal force that means the ball would stop as soon as it encounters the slope due to the infinitely greater frictional loss (read complete loss of energy to friction), which is not the case. So it has to be finite, but even so not...

    I Distance traveled by a ball down a ramp and on a flat path

    Well, both the LHS and RHS are equal to mgh per the mentioned equations, so that is pretty straightforward.

    I Distance traveled by a ball down a ramp and on a flat path

    The friction may be slightly greater only for an instant during which the ball transitions to going up the slope. The additional force you are talking about is just the higher normal force for that instant induced by the slope the ball encounters. Also the total frictional loss on the up-slope...

    I Distance traveled by a ball down a ramp and on a flat path

    It is not a trivial result. Let me use your words to rephrase the question. If -the distance the ramp ball travels without the ramp is F -the distance it travels with the ramp is R Then it follows that the difference between the two is F-R....However, if F is unknown, can one just roll the ball...

    I Distance traveled by a ball down a ramp and on a flat path

    Thank you, so that would mean the current formula for kinetic energy in the above equations be replaced with the linear + rotational kinetic energy formula, but that would not change the derived results.

    I Distance traveled by a ball down a ramp and on a flat path

    Question: A ball is hit with a certain force and it starts with an initial velocity of V m/sec decelerating due to friction along a flat path and then up an inclined ramp coming to stop at the top of the ramp where the ramp becomes flat again (as per diagram A). The total distance traveled along...
