A) Batman and Robin are attempting to escape that dastardly
villain, the Joker, by hiding in a large pool of water (refractive
index nwater = 1.333). The Joker stands gloating at the edge of the
pool. (His makeup is watersoluble.) He holds a powerful laser
weapon y1 = 1.47 m above the surface of the water and fires at an
angle of A?¸1 = 28.4 Ac—¦ to the horizontal. He hits the Boy Wonder
squarely on the letter Ac€A?RAc€??, which is located y2 = 4.83 m below the
surface of the water. How far (horizontal distance) is Robin from
the edge of the pool? (Fear not, Batfans. The Ac€A?RAc€?? is made of
laser-reflective material.) Answer in units of m.

B) Batman attempts to hide out in a Batbox. The top is a
mirrored surface, but the vertical sides are made of clear
Batplastic (refractive index np = 1.333). It is located x = 3.48 m
horizontally from the edge of the pool. What is the minimum depth
(measured to the top of the Batbox) that the Batbox can be below
the surface of the water for the Caped Crusader to remain hidden
from the Joker? Assume: The Joker gets down close to the water for
the best view. Answer in units of m.
