Two gunds, situated on the top of a hill of height 10m, fire one shot each with the same speed `5sqrt(3) ms^(-1)` at some interval of time. One gun fires horizontally and other fires upwards at an angle of `60^(@)` with the horizontal . The shots collide in air at a point p. find (i) the time interval between the frings and (ii) the co-ordinates of the point P. Take origin of the hill right below the muzzle and trajectories in x-y plane.
