Answer:
The kinetic energy of the roller coaster is 1600000 J.
Step-by-step explanation:
Given:
Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.
Now, we need to find the kinetic energy
of the roller coaster.
So, Mass of roller coaster (m) = 8000 N.
Velocity of roller coaster (v) = 20.0 m/s.
Now, putting the formula of kinetic energy:





Therefore, the kinetic energy of the roller coaster is 1600000 J.
Diagonals of rectangles are equal. AC = BD, so 2(x-3) = x+5. 2x - 6 = x+5. x = 11. Plug this into x+5 and you get 11 +5 = 16.
Answer:

Step-by-step explanation:
the third option correctly shows 10 times the square root of 5 (10
)
Answer:
The two possible outcomes are 4 and -12, so 4
Step-by-step explanation:
I’ll explains in the best way I can. Imagine the 3rd one but on the bottom square add one on the left and then one under that. So you would add a total of 2 squares. Hope this helps :)
