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 .
The angle ( in degrees) between the initial and final velocity of rain drops with respect to ground.
