Dan hits a hockey puck, giving it an initial velocity of 3.0m/s. If the coefficient of kinetic friction between ice and puck is0.020, How far will the puck slide before stopping?
Light of frequency 6.0 x 10^14 hertz strikes a glass/air boundary at an angle of incidence θ1. The ray is partiallyreflected and partially refracted at the boundary, as shown above.The index of refraction of this glass is 1.6 of this frequency. De..
