2017 #5 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #5 from the 2017 AP Physics One exam, focusing on wave pulses traveling in opposite directions on a string. Part A involves plotting the velocity of a point on the string over time, while Part B requires sketching the string's shape when pulses overlap. The tutorial emphasizes the importance of accurate drawings for grading, with no need for equations or explanations. The video concludes with a reminder to draw horizontal lines at zero when necessary.

How should the graph be drawn to represent the velocity of point P from t = 0 to t = 5 seconds?

What are the key points to remember when grading the drawings for this problem?

Discuss the significance of drawing horizontal lines at zero in the graph.
