SUMMARY
The eastward component of an airplane's velocity flying at 750 kilometers per hour, 30 degrees south of east, can be calculated using the cosine function. The correct equation is 750 cos(30 degrees), which yields an eastward velocity of approximately 649.52 kilometers per hour. This calculation is essential for understanding vector components in physics, particularly in the context of motion analysis.
