Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. the green disk is initially at rest and is struck by the orange disk moving initially to the right at voi = 7.05 m/s as in figure a, shown below. after the collision, the orange disk moves in a direction that makes an angle of θ = 35.0° with the horizontal axis while the green disk makes an angle of ϕ = 55.0° with this axis as in figure b. determine the speed of each disk after the collision. vof = m/s vgf = m/s

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.
