I'm trying to model a particle being dropped from a height onto a smooth inclined ramp, sliding down it and then freely falling after it leaves the ramp at the bottom (no friction or air resistance). The model should be as simple as possible.
There are 3 different stages of motion, which I guess need to be modelled separately.
I can use Newton's second law to calculate its acceleration while sliding (second stage of motion), and hence work out its velocity upon leaving the ramp (third stage of motion). Its motion is then that of a projectile, subject only to the force of gravity.
My question is about the first part of the motion, when the object is dropped onto the ramp. What would be the criteria for it to bounce? I'd like the model not to include bouncing. What should my assumptions be? What will be the initial conditions for the second stage of the motion, when the particle starts sliding down?
