A missile is being shot with an initial velocity of 60m/s at an angle of 60 degrees with respect to the horizontal. Located at a distance of 1000 meters from the missile launch, you are located at a height of 150 meters and try to intercept the missile by shotting another one. If your missile's initial velocity of 80m/s, at what angle and how long after the first missile is shot, should you shoot yours?
