When a boy is stationary, he observes that rain drops are falling at `30^(@)` to vertical direction. When he starts running with speed `10m/s`, he observed that rain drops are falling vertically downwards. Calculate the actual velocity of rain drops.

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

A person is walking to the east at 2 km/hr and the rain drops appear to him dropping vertically downwards at 2sqrt(3)km//hr . Find the actual velocity of rain.

A man sitting in a bus travelling in a direction from west to east with a speed of 40km//h observes that the rain-drops are falling vertically down. To the another man standing on ground the rain will appear

A man is running with a speed of 4 m/s, if he feels that rain drops are hitting him vertically with speed 3 m/s (along unit vector -hatj ) then what can be the velocity of rain:

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.

Rain is falling vertically downwards with respect to ground. If a girl running on the ground with speed 3 km/h observes the rain is falling with speed 5 km/h then actual speed of rain 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 moving man is.

A man standing on a road has to hold his umbrella at 30^(@) with the vertical to keep the rain away. He throws the umbrella and starts running at 10km/hr. He finds that rain drop are hitting his head vertically. Find the speed of rain drops with respect to (a) road (b) the moving man.
