Acar moving at constant speed in a straight line with the engine providing a driving force equal to the resistive force f. when the engine is switched off, the car is brought to rest in a distance of 100 m by the resistive force. it may be assumed that f is constant during the deceleration. the process is then repeated for the same car with the same initial speed but with a constant resistive force of 0.800 f. how far will the car travel while decelerating? a. 120 m b. 125 m c. 156 m d. 250 m

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.
