A coyote that is carrying an anvil steps off of a high cliff. Fortunately, the coyote has a parachute so, when it opens, they both fall at a constant velocity of 1500 ft/min.

a) How long does it take the anvil to hit the ground?
b) What is the velocity of the anvil right before it hits the ground?

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.
