conserve momentum:
0.600(+4.00) + 1.00(-5.00) = 1.00(-7.25) + 0.600v
v = +7.75
Now, what's wrong with this picture?
A 0.600-kg ball traveling 4.00 m/s to the right collides with a 1.00-kg ball traveling
5.00 m/s to the left. After the collision, the lighter ball is traveling 7.25 m/s to the
left. What is the velocity of the heavier ball after the collision?

(0.600*4.00+1.00*(-5.00)-0.600*(-7.25))/1.00 = 1.75
I put parenthesis just to show the negative numbers, but the whole problem should be put in the parenthesis then divide by 1.00 in a calculator
