Question

Light from the Sun reaches Earth in 8.3 min. The speed of light is 3.00 x 10^8 m/s. How far is Earth from the Sun?

GIVEN:
t = 8.3 min
V = 3.00 x 10^8 m/s
--> Would acceleration be 9.81 m/s^2?

Is it this equation

d = Vit + 1/2 a t^2

Answer 1

You do not need to use the acceleration of gravity to answer this question.

Distance = (wave speed) x (time)

= V t

Do the multiplication.
