An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45° relative to edge of the sidewalk. if it has traveled 1 m perpendicular to the edge of the sidewalk, how long has it been walking?

a.) 0.07 s

b.) 5 s

c.) 14 s

d.) 45 s

14 s

Explanation:

Given

Velocity of ant is 0.1 m/s in a direction

if it has traveled 1 m perpendicular to the edge of the sidewalk

i.e. from diagram

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
