study the image of the roller coaster, then answer the questions. note that the arrows indicate the direction of the movement of the roller coaster train. which section (a or b) of the roller coaster shows positive acceleration? which section (a or b) of the roller coaster shows negative acceleration?

study the image of the roller coaster, then answer the questions. note that the arrows indicate the direction of the movement of the roller coaster train. which section (a or b) of the roller coaster shows positive acceleration? which section (a or b) of the roller coaster shows negative acceleration?

Answer

Explanation:

Step1: Understand acceleration concepts

Positive acceleration is when speed increases, negative is when speed decreases.

Step2: Analyze section A

As the roller - coaster goes down section A, its speed increases due to gravity pulling it downwards, so it has positive acceleration.

Step3: Analyze section B

As the roller - coaster goes up section B, gravity acts against its motion, causing its speed to decrease, so it has negative acceleration.

Answer:

Which section (A or B) of the roller coaster shows positive acceleration? A Which section (A or B) of the roller coaster shows negative acceleration? B
