An object is thrown at an angle of 30 degrees with an initial speed of 50 m/s. What is the horizontal component of the velocity?.
- A.43.30 m/s
- B.25 m/s
- C.50 m/s
- D.15 m/s
Model answer
What a good answer should say
- 43.30 m/s
Explanation
Why this works
The horizontal component is calculated using: Vx = V * cos(θ). Substituting gives Vx = 50 * cos(30°) = 50 * 0.866 = 43.30 m/s.
