Hello.
I can't see how i'm meant to do this, could anyone point me in the right direction?

Two particles A and B are in a collision. A is moving at 5ms-1, B is moving at 7ms-1 in the opposite direction. The coefficient of restitution is 0.8.

Any ideas?
I need the speeds after the collision

Cr = (V2f - V1f) / (V1 - V2)

what are you trying to find? you need more information to find the final velocities.

also is it a static or elastic collision, do the two particles stay together
#5
if the two particles stay together after collision than their velocity would be -1.6, I believe
#6
the particles dont stay together
the particles (i think) have the same mass

so far i think the questions written badly, cos i cant see anything ive missed, im just checking with you guys before i hand it in.

if it was elastic the coefficient would be 1, if it was inelastic it would be 0 and they would stick together.

thats perfectly elastic or inelastic
this is 0.8, so its quite elastic
(way we've been taught to think of it)
