Elastic Collision lab. I'm trying to calculate velocity, momentum, and kinetic energy in an elastic collision. The data I have is this. I tried using these numbers to calculate velocity and momentum but the results show momentum is not conserved as it should be. Is that just error from measurements or am I missing something?

1. Show that the Kinetic Energy and the Momentum are conserved in this system. (Remember that momentum is a vector, so you need to show the conservation of the momentum in x and y directions separately.) Data: Before the collision: m1= 1kg v1x =1 m/s v1y=0 m/s m2=1kg v2x=-1m/s v2y=0 m/s After the collision: m1= 1kg v1x =-0.778 m/s v1y=-0.629 m/s m2=1kg v2x= 0.778 m/s v2y=0.629 m/s 2.
