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
I think it is 5.64 I hope this helps
Answer:21 I used math. way. it is a great app
you do 5-12= -7x-3=21 . in the calculator you don't need the (-s)
Answer:84
Step-by-step explanation:
Okay. Are you taking calc? Dv/dt =d/dt(L(t)^3)=d/dt[(sqrt(14)+2t)^3]= 6(Sqrt(14)+2t)^2)=44. We defined t=0 to be time at which length is sqrt(14). Does that work?
Answer: 4.1 cups of flour
Step-by-step explanation: Each cookie contains 0.125 of flour. If Megan wants 2.75 times as many cookies as the recipe calls for she would have to make 33 cookies. 0.125 x 33 = 4.1 CUPS OF FLOUR.
