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?

An image showing a particle's trajectory on a cartesian plane (x versus y). For negative y-coordinates, the particle follows a concave down trajectory with positive x-coordinates. At the x-axis, the particles trajectory is parallel to the x-axis. For positive y-coordinates, the particle follows a concave up trajectory with positive x-coordinates.

Answer Section#

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