A particle of mass $m$ is attracted towards $O$ on a straight line by a force $m ω^{2} x$ ( $x$ is the distance from $O$ ). At $t = 0$ , $x = a$ and the velocity is $u$ away from $O$ . Its position at time $t = \frac{π}{2 ω}$ is:

Options:

Answer:

Solution:

$x = a cos ω t + \frac{u}{ω} sin ω t$ . At $ω t = π /2$ : $x = u / ω$ .
