A particle of mass 'm' is moving in time 't' on a trajectory given by
\(\overrightarrow r = 10\alpha {t^2}\widehat i + 5\beta (t - 5)\widehat j\)
Where \(\alpha\) and \(\beta\) are dimensional constants.
The angular momentum of the particle becomes the same as it was for t = 0 at time t = ____________ seconds.
