Though the rain is falling vrrtically down-wards, the fromt screen ot a moving car gers wet while the back screen remains dry. Whay ?

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?

A car is moving on a road through vertical rainfall . Both the windscreens at the front and the rear are vertical. The front windscreen gets wet in the rain but the rear screen remains dry . Explain the observation.

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 :

A girl riding a bicycle with a speed of 5 m//s to wards Noth direction, observes rain falling vertically down. If she increases her speed to 10 m//s , rain appeard to meet her at 45^@ to the vertical . What is the speed ot the rain ? In what direction does rain fall as observed by a ground based observer ?
