Exam-style question
Try this first
A projectile is launched with an initial velocity of 20 m/s at an angle of 30 degrees to the horizontal. Calculate the range of the projectile. Assume no air resistance.
Model answer
What a good answer should say
- The range of the projectile is 40 m.
Explanation
Why this works
This question tests the ability to apply the range formula for projectile motion. The formula used is R = (v^2 * sin(2θ)) / g.
The substitution and calculations show how the initial velocity and angle affect the range.
