GO In Fig. 33-51, light is incident at angle θ 1 = 40.1° on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n 1 = 1.30, n 2 = 1.40, n 3 = 1.32, and n 4 = 1.45, what is the value of (a) θ 5 in the air and (b) θ 4 in the bottom material? Figure 33-51 Problem 51.

5.97 Block A, with weight
3w, slides down an inclined plane
S of slope angle 36.9° at a constant
speed while plank B, with weight
w, rests on top of A. The plank
is attached by a cord to the wall
(Fig. P5.97). (a) Draw a diagram
of all the forces acting on block
A. (b) If the coefficient of kinetic
friction is the same between A and
B and between S and A, determine
its value.
