A 2.40 kgkg can of coffee moving at 1.50 m/sm/s in the +x+x-direction on a kitchen counter collides head-on with a 1.20 kgkg box of macaroni that is initially at rest. After the collision the can of coffee is moving at 0.825 m/sm/s in the +x+x-direction. What is the velocity (magnitude and direction) of the box of macaroni after the collision? Express your answer to three significant figures and include the appropriate units. Enter positive value if the box is moving in the +x+x-direction and negative value if the box is moving in the −x−x-direction.
