A man is travelling at 10.8 kmph in a topless car on a rainy day. He holds an umbrella at an angle of 37^@ with the vertical to protect himself from rain which is falling vertically downwards. What is the velocity of the rain drop ?

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?

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

There are two incline planes AO and OB inclined at 45^(@) and 60^(@) respectively with the horizontal as shown in the figure. When a man moves on the inclined plane AO he is oberves that the rain drops are falling 45^(@) with the vertical. When the man moves on the inclined plane OB , he observes that the raindrops are falling vertically downward with the horizontal. Then actual speed of rain is

A man runs along a horizontal road on a rainy day. His umbrella vertical in order to protect himself from the rain then rain actually

To a stationary man, rain appears to be falling at his back at an angle 30^@ with the vertical. As he starts moving forward with a speed of 0.5 m s^-1 , he finds that the rain is falling vertically. The speed of rain with respect to the moving man is.

To a stationary man, rain appears to be falling at his back at an angle 30^@ with the vertical. As he starts moving forward with a speed of 0.5 m s^-1 , he finds that the rain is falling vertically. The speed of rain with respect to the stationary man is.

A man moving with a velocity of 5m//s on a horizontal road observes that raindrops fall at an angle of 45^(@) with the vertical. When he moves with a velocity of 16m//s along an inclined plane, which is inclined at 30^(@) with the horizontal , he observes raindrops falling vertically downward as shown in the figure. Find the actual velocity of the raindrops.

A person is walking in rain feels the velocity of rain as twice to his velocity. At which angle he should hold the umbrella with vertical if he moves forward, if it is raining vertically downwards

Statement -1 : A man standing on the ground has to hold his umbrella at an angle theta with the vertical to protect himself from rain. It is possible that the man now starts running on the ground with certain speed, but he still has to hold his umbrella at angle theta with the vertical to protect himself from rain. Statement -2 : Vertical component of velocity of rain w.r.t man does not change. if he starts running on a horizontal ground.
