A man travelling at `10.8 kmph` in topless car on a rainy day. He holds an umbrella at angle of `37^(@)` with the vertical so that he does not wet.If rain drops falls vertically downwards what is rain velocity.

A man moving in rain holds his unbrella inclined to the vertical even though the rain drops are falling vertically downwards . Why ?

A glass wind screen whose inclination with the vertical can be changed is mounted on a car. The moves horizontally with a speed of 2m//s . At what angle alpha with the vertical should the wind screen placed so that the rain drops falling vertically downwards with velcoity 6m//s strike the wind screen perpendicularly?

To a man walking at 5kmph rain appears to fall vertically, and when he doubles his speed it appears to make an angle of 30^(@) with the vertical. Find the actual velocity of the rain. In what direction will rain appear to fall if the man suddenly turns around when his speed is 5 kmph?

A car which has front and rear glass screens almost vertical is moving on a road when rain drops' are falling vertically downward. The rain will strike:

When a man moves down the inclined plane with a constant speed 5 ms^-1 which makes an angle of 37^@ with the horizontal, he finds that the rain is falling vertically downward. When he moves up the same inclined plane with the same speed, he finds that the rain makes an angle theta = tan^-1 (7/8) with the horizontal. The speed of the rain is

A man walks in rain with a velocity of 5 kmph. The rain drops strike at him at an angle of 45^(@) with the horizontal. The downward velocity of the rain drops will be :

A man is going in a topless car with a velocity of 10.8kmph."l It is raining vertically downwards.He has to hold the umbrella at angle 53^(0) to the vertical to protect himself from rain.The actual velocity of the rain is (cos53^(0)=(3)/(5))
