There must be 2 lines on every plane because you need a y-axis and an x-axis.
No it is not. They are the wrong points
<span>-6x - 2 = 40
-6x = 42
x = -7

I can figure out this is a frefall motion.
Starting from rest => Vo = 0
Then, use the equation: d = [1/2]gt^2 => t = √(2d/g)
d = width of a black/clear stripe pair = 5cm = 0.05m
g ≈ 10 m/s^2 (the real value is about 9.81 m/s^2)
t =√(2*0.05m/10m/s^2) = 0.1 s
Answer: approximately 0.1 s
The decimal for this fraction is 5.5
