Free Fall

  1. Jul 31, 2012 #1
    An object is thrown vertically up from the top of a tower with an initial velocity of 29.4m/s. Four seconds later another object is drop from the top of the tower. How many seconds will the two be at the same level?



    I'm trying to solve it for a day already. Sorry, I suck at this :P

    Well, try coming up with functions for position in terms of time using our basic laws of kinematics. Then set the two equal and solve.
