Hiya, say I have a ball that I throw in the air in an arc, I want to slow it down in the air by air resistance and on the ground by friction - oh and it needs to bounce. I'm assuming no wind.
I know the ball could have all sorts of different textures that may affect the air resistance and friction, so assume it's pretty smooth like plastic (not like a polished thing). Also assume the ground is very well maintained short grass without unusual bumps, not a mirror smooth surface.
Naturally I'll be applying gravity and making it bounce (I'll set the ball up with an appropriate Young's Modulus).
I'm wondering if it's worth applying air resistance at all or if it'll be such a low amount as to not be worth bothering.
Mainly the ball needs to slow down when rolling on the ground towards the end but should I retard the horizontal velocity as a result of it bouncing? (probably should do) Naturally I'll be changing the vertical velocity as a result of the bounce. Then they'll be a point when it ceases to bounce and just rolls and that's when my friction really kicks in, so I need a realistic value.
I know I could go more complex than this by introducing spin, but I want to keep it simple.
Assume ball is moving in metres per second so the friction values can be related to that.
Any suggestions appreciated, thanks!
