1The time of flight of a projectile launched at u and angle θ is

2A stone is thrown horizontally at 20 m/s from a cliff 45 m high. How far from the foot of the cliff does it land? (g = 10 m/s²)

3A ball is projected at 10 m/s at 45° to the horizontal. Find its maximum height, to 2 decimal places. (g = 10 m/s²)

4A ball is projected at 40 m/s at 30° to the horizontal. Find its time of flight, to 2 decimal places. (g = 10 m/s²)

5The maximum range of a projectile launched at 10 m/s (g = 10 m/s²) is ___ m.

6The maximum range of a projectile launched at 50 m/s (g = 10 m/s²) is ___ m.

7The path of a projectile is a

8A ball is projected at 40 m/s at 60° to the horizontal. Find its range, to 1 decimal place. (g = 10 m/s²)

9The horizontal range of a projectile is

10The maximum range of a projectile launched at 15 m/s (g = 10 m/s²) is ___ m.
