A sports car moving at constant velocity travels 120m in 5.0s. If it then breaks and comes to a stop in 4.0s, what is the magnitude of its acceleration (assumed constant) in m/s^2, and in g's (g= 9.80 m/s^2)?

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.
