2016 #3 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #3 from the 2016 AP Physics One exam, focusing on a cart moving down an inclined track with speed bumps. It explains how to graph the cart's velocity over time and discusses the effects of changing bump distance and ramp angle on the cart's speed. The tutorial also evaluates a proposed equation for average speed, testing its validity with experimental data and discussing the importance of correct reasoning in physics problem-solving.

What happens to the average speed of the cart after reaching the 40th bump?

Describe the motion of the cart between bump 41 and bump 44.

What is the significance of the average velocity line in the velocity graph?

What assumptions can be made about the acceleration of the cart between bumps?

How does the negative acceleration caused by the bumps affect the cart's motion?

How does the distance between the bumps affect the cart's maximum speed?

Why is it important to explain reasoning when answering physics questions?

Explain how the angle of the ramp affects the maximum speed of the cart.

Discuss the relationship between mass and average speed according to the student's equation.

Evaluate the student's equation for average speed. What are its limitations?
