The airplane has a bearing of 30 west of north at a speed of 500 miles per hour. As the airplane reaches a certain point, it encounters a wind with a velocity of 70 miles per hour in the direction of 45 east of north. What are the resultant speed and direction of the airplane? 522.5 miles/hour; 112.60 567.9 miles/hour; 112.6 567.9 miles/hour; 157.40 522.5 miles/hour; 157.40 QUESTION 4 10 points Save Answer A wagon is being pulled by a handle making a 40 angle with a force of 35 pounds.
