Homework Statement
The airspeed of a small plane is 200 km/h. The wind speed is 50.0 km/h [E]. Determine the velocity of the plane
relative to the ground if the pilot keeps the plane pointing in each of the following directions.
a) East (250 km/h [E] )
b) West (150 km/h [W] )
c) North (206 km/h [N14.0°E])
d) North 40° East (2.4e2 km/h [E41°N] )
Homework Equations
Sin Theta = opp/hyp where Theta = 40 deg, Hyp=200.
The Attempt at a Solution
The first three are basic. For the fourth obviously, a simple resolution of vectors won't do. If I do, I get 128, while the answer is 240. What am I doing wrong?
Sorry to sound so stupid, I am a novice at physics.
