These are extremely basic questions. You should have some idea of what the answers are already. If someone just told you the answers, you probably would not learn or remember a thing.
Have you learned about sine and cosine functions? Do you know what a "component" of a vector is?
I'd like to hear what you think the answers are before going any farther.
The launching velocity of a projectile is 20 m/s at 53 degrees above the horizontal. What is the vertical component of its velocity at launch? Its horizontal velocity? Neglecting air friction, which of these components remains constant throughout the flight path? Which of these components determines the projectile's time in the air?
Please Help!!
Thanks!

Vertical : 20
When the vector is given you would multiply the vector times the cos of the degrees of the horizontal side and multiply the vector and the sin of the same degrees to get the vertical side
