38. Calculate the initial velocity of a 1.00 kg artillery shell that is moving north when it explodes into three fragments: 0.200 kg moving 500 m/s east, 0.500 kg moving 566 m/s north east, and a third piece moving 1000 m/s. 39. A 300-gram model airplane is flying 15.0 m/s straight north when a gust of wind applies a force of 75.0 N west on the airplane for a time of 80.0 ms. Calculate the velocity the airplane will have as a result of the gust of wind.
