# Can anyone help me with these momentum problems anything with x is the value that needs to be found thanks?

Elastic Momentum:
before collision:
1) m1 = 2kg; m2 = 2kg; v1 = 1.5 m/s; v2 = x; p(total) = 0
after collision:
v1 = -1.5 kg*m/s; v2 = 1.5 kg*m/s;
total momentum after collision:
p(m1)+p(m2) = 0 kg*m/s
before collision:
2) m1 = 2.5kg; m2 = 5kg; v1 = x ; v2 = -1m/s; p(total) = 0 kg*m/s
after collision:
