Question

1. at what point on this diagram would the roller coaster have the most kinetic energy? (the roller coaster is moving from left to right) 1 point

Explanation:

Step1: Recall kinetic - energy principle

Kinetic energy is related to speed. The lower the height of the roller - coaster, the more potential energy is converted to kinetic energy, and the higher the speed.

Step2: Identify the lowest point

Among points A, B, C, and D, point B is the lowest point. So it has the most kinetic energy.

Answer:

point B
