A ball is projected from a point on ground with speed 50m/s at an angle of 37° with the horizontal. The ball is projected towards a wall A at a distance of 40m. There is another wall at a distance of 60m from wall B. On each collision the horizontal velocity of the wall is reversed and the vertical velocity remains unchanged. Find the time of flight of the ball, number of collisions and the distance from wall B where the ball lands again on ground.
