What is its speed after impact

Reference no: EM13531777

A cart with mass 310 g moving on a frictionless linear air track at an initial speed of 1.4 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 the mass (in g) of the second cart?

(b) What is its speed after impact?
