Concept Question

    Hey, I had a basic conception question about projectile velocity. When a projectile reaches its highest point, does the velocity of the projectile equal 0 or does it equal the initial x velocity? I know that Vy=0 at the highest point of a projectile's trajectory, but I'm not sure about the other component(s). Does this also go for the acceleration of the projectile?

    When a projectile reaches its highest point you are correct in that its y component of velocity is zero. The x component however is unchanged. A projectile will be subject to a constant acceleration due to gravity.

    Does that mean that the velocity of a projectile at the highest point of its trajectory will be whatever the initial X velocity is?

    Yes. The acceleration is always constant.
