An aeroplane is flying horizontally at 45 m/s at a height of 780 m. It is to drop supplies to people cut off by flood waters. a. Determine how long before the plane reaches the point directly above the people that the plane much drop the supplies. b. Determine the distance before being directly over the people that the supplies must be dropped at. c. Determine the velocity of the supplies just before they hit the ground.
