Two carts on a track with negligible friction collide and stick together. The first cart with a mass of 0.550 kg was moving initially to the right with a velocity of 1.33 m/s and hits the second cart at rest with a mass of 0.350 kg. What is the initial momentum of the two cart system? b. What is the final velocity of the two carts after the collision?

c. Explain what type of collision this is and how you can tell.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
