Position XY 5a#

Part 1#

A particle’s path follows the trajectory shown in the figure. Which of the following statements is correct?

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

Answer Section#

  • For \(x<0\), the particle’s instantaneous acceleration is non-zero.

  • For \(x<0\), the particle’s instantaneous velocity is constant.

  • For \(x<0\), the particle’s instantaneous velocity is in the \(\hat{\imath}\) and \(\hat{\jmath}\) directions.

  • For \(x<0\), the particle’s instantaneous acceleration is in the \(-\hat{\imath}\) and \(\hat{\jmath}\) directions.

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