An air-track cart with mass m1=0.34kg and initial speed v0=0.80m/s collides with and sticks to a second cart that is at rest initially.

Part A If the mass of the second cart is m2=0.54kg, how much kinetic energy is lost as a result of the collision? Express your answer to two significant figures and include appropriate units.
