Suppose I throw a ball at a wall parallel to its x-axis.
At the moment it hits the wall, what forces are acting upon the ball?
None. Relevant assumptions: ignore any spin on ball.
The Attempt at a Solution
I think they'll be:
- gravity acting in the negative y-axis direction
- friction acting in the positive y-axis direction
- friction acting in the negative x-axis direction.
Friction may be kinetic or static depending on whether ball slips while bouncing?
Have I missed anything? Or included something falsely? I'm pretty sure that there's a friction force in the negative y-axis direction, but not entirely sure, since the ball's path will be arcing downwards with gravity.
