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
Answer:
- 35
Step-by-step explanation:
2(x - 7) = 3(x+7)
2x - 14 = 3x + 21
- 21 - 14 = 3x - 2x
x = - 35
Rechecking :
2(-35 - 7) = 3 (-35 +7)
- 84 = - 84
I hope im right!!!
Answer:
its 6.40
Step-by-step explanation:
you have to use the distance formula which is

so points C is (-5,-1) and D is (0,3)
then you substitute the x
0--5=5^2
then
3--1+4^2=16
25+16=41
then square rout that and it equals 6.40
