Question

Consider the roller coaster on the track. If you want to increase the kinetic energy of the roller coaster as it proceeds through the course, what is the FIRST thing you should do?
A) Increase the height at point A.
B) Decrease the height at point A.
C) Increase the height at point B.
D) Decrease the height at point B.

Answer 1

Answer:

The answer is A and D but if you want one anwer i think the anwer is A

Explanation:

Answer 2

Increase the height at point A will increase the kinetic energy of the roller coaster. Option A is correct.

What is kinetic energy?

The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.

According to the law of conservation of energy, the total energy is defined as the sum of kinetic energy and potential energy.

Total energy = kinetic energy+energy+potential energy

Also, the energy can not be created nor be destroyed can be transferred from one form to another form.

Work =  Force × distance

Kinetic energy = work = weight  × height traveled

Increase the height at point A will increase the kinetic energy of the roller coaster.

Hence, option A is correct.
