Answer»

Since the ELEVATOR is moving with constant VELOCITY, the FRAME of elevator is inertial.

The only force acting on COIN gravity.

Now in reference of elevator,

$s=ut+\frac{gt^2}{2}\\2.45=0+\frac{9.8t^2}{2}\\2.45=4.9t^2\\t^2=0.5\\t=\sqrt{\frac{5}{10}}\\t=\sqrt{\frac{1}{2}}\\t=\frac{1}{\sqrt2}$
