two guns are pointed at each other one upward at 30° and other at same angle of depression. The nozzle being 30m apart. Of the guns are shot with a velocity of 350 m/s upward and 300m/s downward. Find when and where they will meet.
We have:
"v_1\\cos{30\\degree}t+v_1\\cos{30\\degree}t=x"
"t=\\frac{30}{(350+300)cos{30\\degree}}=0.053\\ s"
The distance from first gun:
