In the given figure points A and C are on the horizontal ground & A and B are in same vertical plane. Simultaneously bullets are fired from A, B and C and they collide at D. The bullet at B is fired horizontally with speed of `72/5 km//hr` and the bullet at C is projected vertically upward at velocity of `54/5 km//hr`. Find velocity of the bullet projected from A in `m//s`.

Points A and C are on the horizontal ground and A and B are in same vertical plane at a distance of 1500 m . Simultaneously bullets are fired from A,Bll and C and they collide at O . The bullets at B is fired at an angle of 30^(@) with horizontal towards the ground iat velocity 100 m//s . the bullet at C is projected vertically upwards at velocity of 100 m//s . the bullet projected from A reaches its maximum height at O . Find the time in which bullets will collide (seconds ):
