The particles in the figure below (m1=1.6 kg and m2=3.5 kg) undergo an elastic collision in one dimension. Their velocities before the collision are v1i=12 m/s and v2i=-7.5 m/s. Find the velocities of the two particles after the collision. (Indicate the direction with the sign of your answer.)
V1f=____m/s
V2f=____m/s
Can someone please help me with this problem as it's on my hw and due on tuesday..Thank you for any help....
