Airplane dropping goods

  1. Sep 16, 2008 #1
    I am trying to drop goods to a ridge of a mountain. The height from the ground to the plane is 203 m. The distance from the plane to the ridge is X. If plane is traveling at 65.278 m/s, how far in advance (horizontal distance) must the goods be dropped?

    -Should I calculate Vxo since Vyo would be 0? Then figure out what the horizontal distance would be?

    Using same info, what if now 441 m in advance of drop zone, what vertical velocity should supplies be given to hit drop zone?

    The technique is generally to calculate the time the object will take to fall the appropriate distance (assuming no air resistance and falling at 'g')
    You then use this time together with the constant horizontal speed to calculate the horizontal distance
