In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.
Answer:
$12 per hour
Step-by-step explanation:
I did the math
First, use division to determine the unit rate of one cookie (sorry if terminology is wrong, but i do know how to do it).
Little town = 9/$8 = $1.125 per cookie
College town = 30/$13 ≈ $2.3076 per cookie
Now we are sure of how much each costs and can determine how much she would have spent at each place.
Little town= $1.125*10= $11.25
College town= $2.3076*10≈ $23.08
Now, subtract little town from college town to figure out the savings.
23.08-11.25= $11.83
Thus, she saved $11.83.
C. ΔKPT ≈ ΔKRT
It's identical on both sides.
