ufo is trying to escape by flying at the constant velocity of 70m/s at an upward angle of 2 degrees. it passes directly over you at a height of 40 m. at the instant it is directly above you you attempt to shoot it down by launching a projectile.

what is the lowest launch speed for initial velocity you could use to successfully hit the ufo? and at what angle would you launch at?
