Problem 2: Suppose a man stands in front of a mirror as shown in the figure. His eyes are 1.65 m above the floor, and the top of his head is 0.11 m higher.

Randomized Variableshe = 1.65 m
hh = 0.11 m Part (a) Find the height above the floor of the bottom of the smallest mirror in which he can see both the top of his head and his feet. Part (b) Find the height above the floor of the top of the smallest mirror in which he can see both the top of his head and his feet.

Explanation / Answer

a)

hb = he / 2 = 1.65 / 2

= 0.825 m

.

b) ht = he + hh/2

= 1.65 + 0.11/2

= 1.65 +0.055

= 1.705 m
