Question

2.
A man is walking on a road with velocity. Velocity of rain relative to the man
appears to be 2v and the rain is falling down vertically the actual velocity of the
rain is
​

Answer 1

Answer:

(root 5) v

Explanation:

if man has velocity v and rain has velocity 2 v(question not clear btw)

if the man is at rest ie relative velocity(with respect to ground) of rain has y component 2 v downwards and v horizontally in direction of man according to question

so resultant root2( v square + 4 v square)= resultant velocity or actual velocity

sorry cant find symbol fr sq. root in this keyboard

ps we know v is horizontal vel coz, v horizontal (relative to man) is 0 given in question

so man and rain have same horizontal vel. v
