1A jet is flying through a wind that is blowing with a speed

1-A jet is flying through a wind that is blowing with a speed of 55 mi/h in the direction N 30° E. The jet has a speed of 765 mi/h relative to the air. In what direction should the pilot head the plane for the true course to be due north? (Round your answer to one decimal place.)

2- jet is flying in a direction N 10° E with a speed of 500 mi/h. Find the north and east components of the velocity. (Round your answer to two decimal places.)

Solution

the plane sholud travel in North East direction

speed= 765 -55 = 715 mi/h

2). north component = 500 sin10 =86.8 mi/h

east component = 500cos10 =492.4 mi/h
