Question

A man moving with 5 m/s observes rain
falling vertically at the rate of 10 m/s Find the speed and
direction of the rain with respect to ground.​

Answer 1

V of man =10m/s

V of man =10m/s

Relative velocity=20-10=10m/s

Relative velocity of rain wrt man

=10/+and =10√3

speed=√(10)+(10√3)=√100+300=20m/s

Q=60° with ground
