A cannon fires successively two shells from the same point with velocity V_(0)=250m//s , the first at the angle theta_(1)=60^(@) and the second at the angle theta_(2)=45^(@) to the horizontal, the azimuth being the same. Neglecting the air drag, find the approximate time interval between firings leading to the collision of the shells (g=9.8m//s^(2))

A particle is fired from A in the diagonal plane of a building of dimension 20m (length) xx 15m (breadth) xx 12.5 m (height), just clears the roof diagonally & falls on the other side of the building at B .It is observed that the particle is travelling at an angle 45^(@) with the horizontal when it clears the edges P and Q of the diagonal. Take g=10m//s^(2) . The range that is AB will be:
