A helicopter is flying horizontally at 7.5 m/s and an altitude of 17 m when a package of emergency medical supplies is ejected horizontally backward with a speed of 13 m/s relative to the helicopter. Ignoring air resistance, what is the horizontal distance between the package and the helicopter when the package hits the ground?
You can figure the time in air from the 17 m. YOu know the initial horizontal speed( -4.5m/s) find then the distance it goes horizontally. Find the distance the helicopter went in the same time.
