Answer: u²sin²θ / 2g.
- A u²sin²θ / 2g
- B u²sin2θ / g
- C u sinθ / g
- D u² / 2g
Correct answer: A. u²sin²θ / 2g
Explanation: Maximum height H = u²sin²θ / 2g.

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.
