What effect does the mass of a projectile have on the time it's in the air? (Neglecting air resistance)

• The lighter the projectile, the greater the time in the air

• The heavier the projectile, the greater the time in the air

• It has no effect

• The lighter the projectile, the less the time in the air

The vertical acceleration

of any projectile ...

• is always 9.8 m/s².

• is always -9.8 m/s².

• depends on the launch velocity.

• depends on the angle of launch.
