Moving bouncing ball effect for multiple objects

Hi,

I am trying animate a hand drawn piece of art so I am working with raster images in .png format that have been imported from photoshop.

I need around 50 apples to rain down from the sky and bounce off the floor and other objects.

Do I seriously need to animate every single apple manually? Please tell me there is an easier way...

I've come across expressions for bouncing balls (inertia and bounce back) but they only seem to work for 'up and down' type of motions, not 'bouncing ball across the screen' type motions. Am I missing something? All the tutorials for 'bouncing across the screen' show them animating one object manually.

How would you go about animating 50 apples (or anything) in raster format to rain down from the sky with realistic bounce and rolling movement when it hits the floor?

Also, would there be a way to make the apples bounce off each other without manually attending to each and every one?

Thanks for your time!
