Arocket rises vertically, from rest, with an acceleration of 3.6m/s^2 until it runs out of fuel at an altitude of 1500m. after this point, its acceleration is that of gravity, downward. a. what is the velocity of the rocket when it runs out of fuel? b. how long does it take to reach this point? c. what maximum altitude does the rocket reach? d. how much time (total) does it take to reach maximum altitude? e. with what velocity does the rocket strike the earth? f. how long (total) is it in the air?

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.
