  • question_answer Rain is falling vertically downwards with a velocity of 3 km/h. A man walks in the rain with a velocity of 4 km/h. The raindrops will fall on the man with a velocity of:

    A)  1 km/h           

    B)  3 km/h

    C)  4 km/h           

    D) \[5\,km/h\]

    Correct Answer: D

    Solution :

    Relative velocity of the rain wrt man will be 4 km/hr horizontal and -3 km/hr vertical. Hence, resultant velocity will be \[{{({{4}^{3}}+{{3}^{2}})}^{1/2}}\,km/hr=5\,km/h.\] Hence, the correction option is [d].
