A man is going due east with a velocity of `3 kmh^(-1)`. Rain falls vertically downwards at a speed of `10 km h^(-1)`. Calculate the angle at which he should hold his umbrella so as to protect himself from rain.

A man is going due east with a velocity of 5ms^(-1) .It is vertically rainging downwards with a velocity of 4ms^(-1) .At what angle should he hold the umbrella to the vertical so as to protect him self from the rain?

A man walking on a road with a velocity of 5 km per hour encounters rain falling vertically with a velocity of 25 km per hour. At what angle should he holds his umbrella in order to protect himself form the rain?

Rain is falling vertically and a man is moving with velocity 6 m s^-1 . Find the angle at which the man should hold his umbrella to aboved getting wet.

A man is walking on a level road at a speed of 3.2 km^(-1) . Rain drops fall vertically with a speed of 4.0 km h^(-1) . Find the velocity of the raindrops with respect to the man. In which direction, the man should hold his umbrella to protect himself from rain ?

Rain is falling vertically with a speed of 20ms^(-1) ., A person is running in the rain with a velocity of 5 ms^(-1) and a wind is also blowing with a speed of 15 ms^(-1) (both from the west) The angle with the vertical at which the person should hold his umbrella so that he may not get drenched is:

Rain is falling vertically with a speed of 20ms^(-1) ., A person is running in the rain with a velocity of 5 ms^(-1) and a wind is also blowing with a speed of 15 ms^(-1) (both from the west) The angle with the vertical at which the person should hold his umbrella so that he may not get drenched is:
