kindly help

Einswine is sitting in a cart (mass of Einswine + cart = 220 kg) traveling at 5.60 m/s East when he collides with a chicken named Henrica Fermi who is also sitting in a cart (mass of Henrica Fermi + cart = 66.0 kg) and who is traveling at 2.40 m/s West as shown below. After the collision Henrica Fermi has a velocity of 7.60 m/s East. What is the velocity of Einswine immediately after they collide? (Take East to be the positive direction)
