Answer:
The kinetic energy is 20,000\ J
Step-by-step explanation:
The kinetic energy of a body is defined as:
Where <em>m</em> is the mass of the roller coaster car
<em>s</em> is the speed and <em>k</em> is the kinetic energy
We know that 
Then the kinetic energy of the roller coaster car is:
So the first one is 1 square meter of ceiling, and it says 1 square meter of cieling is 10.75. <em>So the first one is just that, 10.75</em>
The second one says 10 square meters, so just multiply 10.75, by 10.
In which case you get <em>107.5.</em> So that's the answer.
Third one, it gives you how many ceiling tiles you have. So you divide the 100 tiles by 10.75, which gives you 9.30232558, which becomes <em>9.3</em>
I'm sure you can figure out the last one.
A. b = 3
B. b = 2
C. b = 4
D. b = 3/2
So, here I state the answer to this problem is (B)
Have a great day.

Answer:
1.5
Step-by-step explanation:
Given
Required
What value cause a stretch
For the function to stretch, then the scale factor must be greater than 1.
From the list of options.
Only 1.5 is greater than 1 i.e. 
Hence, 1.5 will cause a stretch.
D
500(x-2)=200x
500x-1000=200x
300x=1000
x=3.333330 or 3 and 1/3
Propeller distance: 3 and 1/3 * 200 = 666.666667 or 666 and 2/3 miles
