The course and ground speed of a plane are 70 degrees and 400 miles per hour respectively. There is a 60 mph wind blowing from the south. Find the approximate direction and air speed of the plane.
net force = force1 + force2
The Attempt at a Solution
Net Direction = 70-60 = 10
Net Speed = 400- x = 10 x = 410
10 degrees and 410 speed. The teacher said that was wrong though, what am I doing wrong?
