Answer

Explanation:

Step1: Determine angle with x-axis

Angle with -y-axis=60°, so with x-axis=30°.

Step2: Calculate vₓ for two directions

Right: ( v_x = 5\cos(30^\circ) \approx 4.33 , \text{m/s} ); Left: ( v_x = 5\cos(150^\circ) \approx -4.33 , \text{m/s} )

Answer:

A. -4.33 meters/second and +4.33 meters/second
