A man moves on a cycle with a velocity of 4 km/hr. The rain appears to fall on him with a velocity of 3 km/hr vertically. The actual velocity of the rain is

To a person, going eastward in a car with a velociyt of 25km//hr , a train appears to move towards north with a velocity of 25sqrt(3) km//hr . The actual velocity of the train will be

For a man walking towards east with a velocity of "5km/hr" rain appears to fall vertically down.When the man begins to walk towards west with a velocity of "3km/hr" the rain appears to fall at an angle of 60^(0) to the vertical.The magnitude of velocity of the rain when the man stops walking is sqrt((139)/(N)) .Then N is equal to

A man going east in a car with a velocity of 20 km/hr, a train appears to him to move towards north with a velocity of 20 sqrt(3) km/hr. What is the actual velocity and direction of motion of train?
