Part a which projectile spends more time in the air, the one fired from 30∘ or the one fired from 60∘? which projectile spends m
bearhunter [10]
The correct answer is the One fired from from 60° . This is because the projectile fired from 60° has a greater vertical velocity compared to the one fired from 30° and therefore spends more time on air. Vertical velocity is the velocity of a body as it moves upwards, it is normally affected by the gravitational acceleration, however it is not affected by the horizontal velocity.
