Mean is all of the numbers added up and then divided by the number of the numbers. so for example; 32+36+38+39+42+43+44+47+49+50 divided by 10 do that and then group 2, and if you already know how to do that then answer the questions
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.
C²=A²+B²
C²= 7² + 24²
C²= 49 + 576
C²= 625
C=√625
C=25
Answer: 2 yards
Step-by-step explanation: there are 36 inches in a yard so divide 72 by 36 to get 2 which is the answer to the question
