. Which of the following statements are true of the time of flight for a projectile? List all that apply.
4. For the same upward launch angles, projectiles will stay in the air longer if the initial velocity is increased.
T
5. Assume that a kicked ball in football is a projectile. If the ball takes 3 seconds to rise to the peak of its trajectory, then it will take 6 seconds to fall from the peak of its trajectory to the ground.
F
3. For a projectile which lands at the same height that it is projected from, the time to rise to the peak is equal to the time to fall from its peak to the original height.
T
1. The time that a projectile is in the air is dependent upon the horizontal component of the initial velocity.
F
2. The time that a projectile is in the air is dependent upon the vertical component of the initial velocity.
