Homework Help: Double check parabolic trajectory answers

  1. Feb 5, 2008 #1
    1. The problem statement, all variables and given/known data

    As a projectile moves through its parabolic trajectory, which of these quantities, if any, remain constant? (Neglect air resistance. Select all that apply.)
    True acceleration
    True horizontal component of velocity
    False speed
    False vertical component of velocity
    False none of these

    True = Constant
    False = Not_Constant

    Could someone please check my answers to this problem. I want to make sure I don't have any incorrect.

    Many THANKS in advance.
