Core Formulae
Equations of Motion (constant acceleration):
- v = u + at
- s = ut + ½at²
- v² = u² + 2as
- s = ½(u + v)t
Projectile Motion:
- Time of flight: T = 2u sin θ / g
- Maximum height: H = u² sin² θ / 2g
- Range: R = u² sin 2θ / g
- Max range at θ = 45°

At what angle does a projectile achieve maximum range?
A
30°
B
45°
C
60°
D
90°
Maximum range occurs when sin 2θ is maximum, i.e., sin 2θ = 1, so 2θ = 90° and θ = 45°.
