Raindrops are falling with velocity 10root2 m/a making an angle 45 degrees with the vertical the drops appear to be falling vertically to a person running with constant velocity the velocity of raindrops change such that the rain now appears to be falling vertically with root3 times the velocity it appeared earlier to the same person running with same velocity
1. After the velocity of rain drops change the magnitude of velocity of raindrops with respect to ground is
2. The angle between the initial and final velocity of raindrops with respect to ground
