Two guns are projected at each other, one upward at an angle of `30^(@)` and the other at the same of depression, the muzzles being `30m` apart as shown in the figure. If the guns are shots with velocities of `350m//s` upward and `300m//s` downward respectively.where the bullets may meet.

`x=14m,y=8.07m`

`x=4m,y=4.07m`

`x=10m,y=10.07m`

`x=5m,y=18.07m`
