Vedclass · Answer

(C) particle is at rest when its velocity is zero,which means its position does not change with time. This corresponds to a horizontal line on a position-time graph.Looking at the $x-t$ graph,the position $x$ is constant (horizontal line) between $t = 2 \ s$ and $t = 3 \ s$.Looking at the $y-t$ graph,the position $y$ is constant (horizontal line) between $t = 1 \ s$ and $t = 3 \ s$.For the particle to be at rest,both $x$ and $y$ coordinates must be constant simultaneously.Therefore,the particle is at rest during the time interval $2 - 3 \ s$.

During which time interval is the particle described by these position graphs at rest?
