Projectile Motion: Understanding Initial and Final Velocities

[brittanyStein]

my techer didnt finish going through everything and she wants us to teach it to ourselves and i don't understand so please help.

neglecting air resistance, the initial horizontal velocity of a projectile is ______ its final horizontal velocity

is it ...
greater than
less than
equal to
directly proportional

If there is no air resistance what horrizontal forces act on the object after it's thrown

I understand your frustration and I am happy to help you understand projectile motion and initial and final velocities. To answer your question, the initial horizontal velocity of a projectile is equal to its final horizontal velocity. This is because in the absence of air resistance, the horizontal velocity of a projectile remains constant throughout its motion. This means that the initial horizontal velocity that the object is given at the start of its motion will be the same as its final horizontal velocity when it reaches the end of its motion. Therefore, the correct answer to your question is "equal to". I hope this helps clarify your understanding of projectile motion. If you have any further questions, please do not hesitate to ask.
