A wagon is being pulled by a 300 -pound force that makes a 30 degrees angle with the ground. What are the horizontal and vertical components of the force vector?

Since the force makes a 30° angle with the horizontal ground, its horizontal component is 300 cos(30°) ≈ 300(0.866) = 260 pounds. Its vertical component is 300 sin(30°) = 300(0.5) = 150 pounds. Therefore, the horizontal component is 260 pounds and the vertical component is 150 pounds, which is choice D.
