During a rainy day
During a rainy day, rain is falling vertically with a velocity 2m/s A boy at rest starts his motion with a constant acceleration of 2m/s2 along a straight road . Find the rate at which the angle of the axis of umbrella with vertical should be changed so that the rain always falls parallel to the axis of the umbrella.

An aeroplane pilot wishes to fly due west A wind of 100 km h^-1 is blowing towards south. (a) If the speed of the plane (its speed in still air) is 300 km h^-1 in which direction should the pilot head ? (b) What is the speed of the plane with respect tom ground ? Illustrate with a vector diagram.
