2021 F = ma Exam — Question 16

A particle begins at the point x = 0 and moves along the x-axis with initial rightward velocity v0 . Later, the particle reaches the point x = L. The velocity as a function of position during this time interval is shown below. v v0 x L Consider the following three statements. I. The particle instantaneously stops at x = L. II. The particle is uniformly accelerated. III. The particle could be performing simple harmonic motion. Which of these statements are true? — Source: Question 16, 2021 F = ma Exam, © 2021 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
