What is the formula for calculating the range of a projectile launched at an angle?.
- A.R = (v^2 * sin(2θ)) / g
- B.R = (v * t) + (0.5 * g * t^2)
- C.R = v * cos(θ) * t
- D.R = (g * t^2) / 2
Model answer
What a good answer should say
- R = (v^2 * sin(2θ)) / g
Explanation
Why this works
The formula for the range of a projectile is derived from the equations of motion under constant acceleration due to gravity. It shows how the initial velocity and launch angle affect the distance traveled horizontally.
