OK, I think that answers my question. I understand what you mean whe you talk about not being a rigid body, but assuming that it is, it should become airborne, even if at some miniscule degree. So, what would be a good way to show "force" coming off the ramp? Momentum? Velocity? Thanks for...
I understand that. However, in the case of the ramp, the lack of support of the object(skateboard) is instantaneous, right? You have a constant velocity of the skateboard, and thus, a constant vertical velocity. Then, at the top of the ramp, what happens? Do you automatically become airborne...
I suppose this may be a better way to explain it. Let's say you have a skateboarder who goes up a ramp:
Skateboarder weighs 70kg
Total vertical height of ramp is 3 meters
One ramp has a linear ramp and a flat top, as follows:
...o o o o o o
...o
...o
..o
(Disregard the...
Ok, this seems fairly straight forward, but I can't get my head around it. You have an object (0.3kg) with a vertical (up; positive) velocity of 10 m/s. This object's velocity is supported by a rising piston. Once the piston stops it's movement, how do you determine whether the object has...
