Position of a...

Question

Position of a particle moving along $x -$ axis is given by $x = t - 4$ , where $x$ is in meter and $t$ in second. Time (in $s$ ) at which it crosses the origin is

Open in App

Solution

Particle will cross the origin, when $x = 0$

i.e. $t - 4 = 0$

$t = 4 s$

Final Answer: $t = 4 s$
