Maurice directs a beam of light on a sheet of glass at an angle of 51°. what is the angle of refraction in the glass? the refractive index of glass is 1.46.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
