A man is coming down an incline of angle 30∘. When he walks with speed √3m/s he has to keep his umbrella vertical w.r.t. ground to protect himself from rain. The actual speed of rain is 5 m/s. At what angle with vertical should he keep his umbrella when he is at rest so that he does not get drenched?
Rain is falling vertically with a speed of 12ms−1.A cyclist is moving east to west with a speed of 12√3ms−1.In order to protect himself from rain at what angle he should hold his umbrella w.r.t vertical.
A, B, C, D are four trees, located at the vertices of a square. Wind blows from A to B with uniform speed. The ratio of times of flight of a bird from A to B and from B to A is 'n'. At what angle should the bird fly from the direction of wind flow, in order that it starts from A and reaches C.Let
