Kinematics Velocity/Acceleration Problem (Graph)

  1. Sep 23, 2009 #1
    The pictures show cannonballs of two different masses projected upward and forward. The cannonballs are projected at various angles above the horizontal, but all are projected with the same horizontal component of velocity.

    Which of the following statements are true about the situations depicted in the figures above?


    1) At the top, the horizontal velocity of the cannonball is greatest in pictures E and F
    2) The highest vertical height reached is in pictures C and D
    3) The flight of the ball is identical in pictures C and D, independent of the fact that the masses are different
    4)The acceleration of the ball in flight is greater in C and D than it is in A and B
    5) The longest horizontal distance traveled is in pictures A and B

    *I tried 3/4/5 then 4/5 I cant seem to figure this one out any help would be deeply appreciated as I am on my last attempt or else this will be wrong.
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution
