5. A plane flying east with airspeed 500. km/h drops a parcel when the plane is above the target. The wind is blowing toward the northeast at 100. km/h. (a) What is the plane's ground speed? (b) If the pilot wishes the parcel to hit the ground directly southeast of the target, with what velocity perpendicular to the plane (south) must the parcel be thrown? 6. A field goal kicker wishes to make a field goal from the 55-yard line. He kicks the ball 40° from the horizontal. The goal's crossbar is 3.0 m high and 60. m from the ball's initial position. What minimum initial velocity must the ball have in order to clear the crossbar?
