dear prof hwang,

reference a requested made before about
modelling the forces between collision of 2 objects in 1 dimension

i kindly request for an extra feature to be added to your existing above model which ability to vary coefficient of restitution e = 0 to 1 instead of the current e =0 or e=1

the reason is i find this feature not available on both NTNU and OSP
one school teacher wanted some feature that i could no make nicely and was hoping you could add to your model so does i can study it.

my model is here

collision cart, showing ideal e=0 and smaller view space xmin=0 and xmax=1
