Answer the following questions in complete sentence.
1. Why is it that the horizontal motion of a projectile remains constant in the duration of its
motion?
2. At what rate does a projectile accelerate constantly as it moves downward?
3. Based on the diagram, by how much does the vertical velocity of the object increases every
1 second? If the cannonballs' vertical velocity at time 5 seconds is 49 m/s, how fast will it be
moving at time 8 seconds?
4. Why is it that the vertical motion of a projectile changes despite the horizontal motion
remaining constant in the duration of its motion?

Answer:
1.The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity.
2.9.8 m/s/s
Yet in actuality, gravity causes the cannonball to accelerate downwards at a rate of 9.8 m/s/s. This means that the vertical velocity is changing by 9.8 m/s every second.
4.In case of projectile motion the vertical component of particle's velocity changes continuously because of the force acting in vertical direction which is its own weight ( mg ). object ; its horizontal velocity remains constant.
