What is the horizontal component of an initial velocity of 20 m/s at an angle of 30 degrees?.
- A.17.32 m/s
- B.10 m/s
- C.15 m/s
- D.20 m/s
Model answer
What a good answer should say
- 17.32 m/s
Explanation
Why this works
To find the horizontal component, use the formula: Vx = V * cos(θ). Substituting the values gives Vx = 20 * cos(30°) = 20 * 0.866 = 17.32 m/s.
