Aball at rest starts rolling down a hill with a constant acceleration of 3.2 meters/second. what is the final velocity of the ball after 6.0 seconds?

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).

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
