Homework Help: Compare acceleration to free fall acceleration

  1. Mar 2, 2006 #1
    i have this problem i cant seem to get i think i am overthinking but just cant get it what is. this is a one dimensional motion with constant acceleration.what is the acceleration of a space capsule fired from a 220m long cannon with a launch speed of 10.97km/s

    Nevermind I've got it now. If you assume the launch speed it the velocity at the then off the barrel you need to use a kinematic equation. Can you think of which one you will need?

    You know that the initial velocity, the final velocity and the distance that it went, there is an equation with those three variables and the acceleration. with that you have an equation with one unknown.
