I want to know the trig maths for calculating the collision normal after collision

[Why_I_Use_Processing]

I want that car shown below in the image to bounce off the tribune after collision.
I already made the collision detections work, I just want to apply some physics after collision(collision normal, velocity component, etc…)

Thanks in advance…

This is not a code writing service. Try something yourself and we’ll tell you why it does not work, but not this way.

What is the “tribune”?

You could start studying this example.
