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:

Step-by-step explanation:
The h and k are the points of the vertex. The h is the one inside the absolute value bars. The k is on the outside. The h has to be the opposite sign from what is on the graph. For example, if the number on the the graph is -1, the number in the <em>equation</em> will have to be a positive 1. The number on the outside stays the same. If the number on the the graph is +1, the number in the <em>equation</em> will also be a positive 1.
Answer:
effective annual rate is 6.16 %
Step-by-step explanation:
given data
rate = 6 % = 0.06
time 5 year = 10 semi annually
to find out
effective annual rate
solution
we know formula for annual effective rate of interest is
rate of interest =
-1
put here all value
rate of interest =
-1
rate of interest =
-1
rate of interest = 0.061646
so effective annual rate is 6.16 %
