# Trajactories

Two guns are mounted on the top of a hill at height $$10m$$. They fire one shot each with the same speed $5\sqrt{3}\ ms^{-1}$ First gun fires at time $$t=0$$ upwards at an angle $$60°$$ with the horizontal. After that firing, at time $$\Delta$$ second gun fires in horizontal direction. If the bullets fired by two guns collide with each other at some time in future, calculate the time interval $$\Delta$$ between the two firings.

Details and assumptions:- 1)Take $$g=10m/s$$

2)Everything is measured in SI units

3)This question is taken from an old IIT test
