362072 A man running along a straight road with uniform velocity \(\overrightarrow u = u\hat i\) feels that the rain is falling vertically down along \( - \hat j\). If he doubles his speed, he finds that the rain is coming at an angle \(\theta \) with the vertical. The velocity of the rain with respect to the ground is

362073 Rain is falling vertically with a speed of \(12\,m{s^{ - 1}}\). A woman rides a bicycle with a speed of \(12\,m{s^{ - 1}}\) in east to west direction. What is the direction in which she should hold her umbrella?

362074 Assertion :
Rain is falling vertically with a certain speed. A boy can hold an umbrella by riding a bicycle does not get wet.
Reason :
The boy is holding his umbrella (at some angle) with the vertical.

362075 A man standing on a road has to hold his umbrella at \(30^\circ \) with the vertical to keep the rain away. He throws the umbrella and starts running at 10 \(km\)/\(h\) he finds that rain drops are hitting his head vertically. Find the speed of rain drops with respect to the ground.
