Homework Help: From what height was an object dropped?

  1. Mar 19, 2009 #1
    Find the height from which you would have to drop a ball so that it would have a speed of 5.9 m/s just before it hits the ground.


    Not sure what I can do with only this much information...

    Well first of all it would help to know what concepts you're currently covering in your physics class because as far as I can tell, this problem can be solved in a few different ways.

    Second of all, what work have you attempted on this problem so far?

    Use one of the kinematic equations. Think what each equation will do for you. Look at you variables and see whats missing. Then try to find that variable by using the kinematic equations.

    Figured it out. Used equation S=(v^2-u^2)/2a
