Two guns situated at the top of a hill of height 10m, fire one shot each with the same speed m/s at some interval of time. One gun fires horizontally and other fires upwards at an angle of 60degrees with the horizontal. The shots collide in air at a point P.
(1) Find the time interval between the firing..
(2) The co-ordinates of the point P.
Take origin of the coordinate system at the foot of the hill right below the muzzle and the trajectories in the x-y plane.
