Answer:
7.68 s
Step-by-step explanation:
The vertical motion formula is:
<u>Where:</u>
h(t): is the final height = 0
h(0): is the height of the cliff = 104 foot
v(0): is the initial velocity = 110 ft/s
g: is the gravity = 9.8 m/s² = 32.15 ft/s²
Hence, from the vertical motion formula we can find the time that will take the rocket to hit the ground:
We have two solutions:
t₁= -0.84 s
t₂ = 7.68 s
We will take the positive value, thus the time that will take the rocket to hit the ground is 7.68 s.
I hope it helps you!
Answer:

Hope this helps <3
for the first truck 1680 / 14 = 120 liters used

Answer:
$29.43
Step-by-step explanation:
Lets have x equal to total price of the packs. To find the total price we need to multiply the price of a singular pack by the amount of packs she bought.
x=3.27*9
Now multiply 3.27 by 9
x=29.43
Justin payed $29.43 for the 9 packs of cards
