Raindrops are falling with velocity `10 sqrt2` m/s making and angle `45^(@)` with the vertical. The drops appear to be falling vertically  to a  man running with constant velocity . The velocity of rain drops change such that the rain drops now appear to be falling vertically with `sqrt3` times the velcoity it appeared earlier to the same person running with same velocity .   After the velocity of rain drops change the magnitude of velocity of raindrops with respect to ground is
