Some day the rain is falling vertically downwards at a speed of 35 m/s and after some time the wind is falling at a speed of 12 m/s.

A man is moving with 10 m//s towards west on a horizontal ground. He observed that the rainfall is falling vertically down wards. Now he increases his speed to 15 m//s and find that now the rainfall at an angle of 45^(@) towards him. The speed of the rain with respect to ground is :

Rain is falling, vertically with a speed of 1m//s .Wind starts blowing after sometime with a speed of 1.732 m//s in east to west direction. In which direction should a boy waiting at a bus stop hold his umbrella?

A man starts running along a straight road with uniform velocity observes that the rain is falling vertically downward. If he doubles his speed, he finds that the rain is coming at an angle theta to the vertical. The velocity of rain with respect to the ground is :

Rain is falling vertically with a speed of 35 ms^(-1) . Winds starts blowing after sometime with the speeds of 12ms^(-1) in east to west direction. At what angles with the vertical should a boy waiting at a bus stop hold his umbrella to protect himself from rain?

A stationary man observes that the rain is falling vertically downwards. When he starts running a velocity of 12 kmh^(-1) , he observes that the rain is falling at an angle 60^(@) with the vertical. The actual velocity of rain is

A ball is dropped from the top of a tower. After 2 s another ball is thrown vertically downwards with a speed of 40 m//s . After how much time and at what distance below the top of tower the balls meet?

A man is walking with 3 m//s, due east. Rain is falling vetically downwards with speed 4 m//s. Find the direction in which man should hold his umbrella, so that rain does not wet him.

Rain is falling vertically down wards with a speed 5 m/s. If unit vector along upward is defined as hatj , represent velocity of rain in vector form.

A man walking with a speed of 3 km/h finds the rain drops falling vertically downwards. When the man increases his speed to 6km/h he find that the rain drops are falling making an angle of 30^(@) with the vertical . Find the speed of the rain drops ( in km/h)
