Try this first
If a projectile is launched with an initial velocity of 20 m/s at an angle of 30 degrees, what is the vertical component of the initial velocity?.
- A.10 m/s
- B.17.32 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
The vertical component can be calculated using the formula v_y = v * sin(θ). Substituting the values: v_y = 20 * sin(30°) = 20 * 0.5 = 10 m/s.
