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//s^(2) 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.

A man is coming down an incline of angle 30 degree . When he walks with speed 2 sqrt3 m/s he has to keep his umbrella vertical to protect hismself from rain. The actual speed of rain is 5m/s . At what angle with vertical should he keep his umbrella when he is at rest so that he does not get drenched ?

A standing man observes rain falling with the velocity of 20 m/ s^-1 at an angle of 30 degree with the vertical. (a) Find the velocity with which the amn should move so that rain appears to fall vertically to him. Now if he further increases his speed, rain again appears to fall at 30 degrees with the vertical. Find his new velocity.
