A cargo plane is flying horizontally at a velocity of 50 m/sec needs to deliver relief supplies to a typhoon devastated area but cannot land because of the damaged runway. The pilot has the option to drop the cargo from a height of 30 meters into a designated drop area. To ensure the supplies will land on the exact spot, what angle of depression must the pilot’s line of sight make at the instant the supplies be released?
