Thank you for the welcome. Okay so an elastic collision means that K is conserved throughout the collision. Therefore: (.5)m1v1i2 = (.5)m1v1f2 + (.5)m2v2f2 But that leaves me in the same situation as before doesn't it?

Homework Statement A cart with mass 340 g moving on a frictionless linear air track at an initial speed of 1.2 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 0.66 m/s. (a) What is...
