CBSE XI Science Physics Motion in a Plane
1. Determine the horizontal velocity u with which a stone must be projected from point p of height h so that it may hit the inclined plane perpendicularly. Inclination is theta and inclined plane is kept just below point p at ground. Give the value in terms of g, h and cot theta. 2. Point A moves uniformly with velocity v so that vector v is continually aimed at point B which in its turn moves rectilinearly with velocity u<v. Initially, u perpendicular to v and separation was l. How soon will the points converge. Plz answer both the questions as I have exam tommorow.

a train is approaching a platform with a speed of 10 km/hr.when it is at a distance of 2 km from the platform breaks are applied so that a uniform retardation is produced. at the same time ,a bird sitting on the pole near the platfiorm flies with the speed of 50 km/hr towards the train touches the front of the train and then returns to the pole.if the motion is repeated until the train comes to rast,the total distance travelled by the bird is?
