Homework Help: Rain and man problem. (relative motion)

  1. Dec 10, 2011 #1
    Please help me with the following problem...

    rain.jpg


    velocity of man wrt to ground is 3km/h due east. velocity of rain with respect to man is 4km/h and falls vertically downwards. If the man moves at 6km/hr then the velocity of rain wrt to man is?

    By using Pythagoras, you can find the actual velocity of rain. And then use it in the next case. Here, as V of rain wrt man is perpendicular to ground, you can constuct a triangle to find actual velocity of rain.
