For this case, the first thing we are going to do is write the generic equation of motion for the vertical axis.
We have then:

Where,
- <em>g: acceleration of gravity
</em>
- <em>vo: initial speed
</em>
- <em>h0: initial height
</em>
For the first body:

For the second body:

By the time both bodies have the same height we have:


Rewriting we have:



Clearing time:

Answer:
it takes 18.31s for the two window washers to reach the same height
Answer:
Side of 22 and height of 11
Step-by-step explanation:
Let s be the side of the square base and h be the height of the tank. Since the tank volume is restricted to 5324 ft cubed we have the following equation:


As the thickness is already defined, we can minimize the weight by minimizing the surface area of the tank
Base area with open top 
Side area 4sh
Total surface area 
We can substitute 


To find the minimum of this function, we can take the first derivative, and set it to 0



![s = \sqrt[3]{10648} = 22](https://tex.z-dn.net/?f=s%20%3D%20%5Csqrt%5B3%5D%7B10648%7D%20%3D%2022)

Answer: 60%
Step-by-step explanation: 24/40 = .6 x 100 = 60
<u><em>Answer:</em></u>
Two thirds of a straight angle is 120°
<u><em>Explanation:</em></u>
<u>First, we start by defining the straight angle:</u>
A straight angle is an angle whose measure is 180°
<u>Now,</u> we want to calculate two thirds of a straight angle
<u>To get that fraction</u>, we will multiply the measure of the straight angle by 
<u>This means that:</u>
of a straight angle =
degrees

Answer: You cannot buy it.
Step-by-step explanation:
$450 with a 20% percent discount would be $360
Add in a sales tax of 5.25%, and it amounts to $549 in total.
Since you only have $400, you cannot buy the bike.
