Aperson is in a room whose ceiling and two adjacent walls are mirrors. how many images are formed? (a) 5 (b) 6 (c) 7 (d) 8

Light rays reflected from a person strike a mirror. The smooth surface of the mirror reflects those light rays back. Some of those rays strike the person’s eyes, and they see the image in the mirror.

So the answer choice is (C) 7

Hope this helped you

Tobey

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
