# Position XY 1d#

## Part 1#

A particle follows the trajectory shown in the figure without stopping along it’s path. What can you conclude aboout the particle’s motion?

• At $$y = 0$$, the particle’s instantaneous velocity points in either the $$\hat{\imath}$$ or the $$-\hat{\imath}$$ direction.

• At $$y = 0$$, the particle’s instantaneous velocity points in either the $$\hat{\jmath}$$ or the $$-\hat{\jmath}$$ direction.

• At $$y = 0$$, the particle’s instantaneous acceleration is zero.

• At $$y = 0$$, the particle’s instantaneous acceleration non-zero.

• No information about the particle’s velocity or acceleration can be found from its trajectory.
