A man is walking due east at the rate of of 4kmph and the rain is falling 30° east of vertical with a velocity of 6kmph the velocity of rain relative to the man will be?
The vertical component of the rain's velocity is
The horizontal component of the rain's velocity is
To the man, the vertical component of the falling rain is
horizontal component of the falling rain is
To the man, the velocity of the falling rain is the resultant of those 2 velocity components:
I hope this helps,
