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:
each child would get 0.625% of a cookie. which is a little over half.
Step-by-step explanation:
8 divided by 5
The bird because it’s going faster also I used a kinetic energy calculator online and the birds came out bigger
Answer:
(4/x)-1
Step-by-step explanation:
The quotient of 4 and the number x means we are dividing 4 by x, so we get 4/x
Then we have the 'one less than' part, meaning we subtract one from (4/x), so we get (4/x)-1
Hope this helps
