A car is traveling east at an unknown initial velocity. Without changing directions, it accelerates at 0.75 m/s2 for a distance of 300 m increasing its velocity to 30 m/s. What was the initial velocity of the car

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).

its c its is a mixture of gases
