While skiing in jackson, wyoming, your friend ben (of mass 69.8 kg) started his descent down the bunny run, 16.8 m above the bottom of the run. if he started at rest and converted all of his gravitational potential energy into kinetic energy, what is ben’s kinetic energy at the bottom of the bunny run? use g = 9.8 m/s 2 answer in units of j.

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.
