To a man running upwards on the hill, the rain appears to fall vertically downwards with `4 m s^-1`. The velocity vector of the man w.r.t. earth is `(2 hat i + 3 hat j) ms ^-1`. If the man starts running down the hill with the same speed, then determine the relative speed of the rain w.r.t. man.
.

A

`sqrt(10) m//s`

B

`2sqrt(10) m//s`

C

`sqrt(20) m//s`

D

`2sqrt(20)m//s`
