Acceleration physics course work

  1. Jun 6, 2009 #1
    A glaucous-winged gull, ascending straight upward at 5.40 , drops a shell when it is 13.5 above the ground. What is the magnitude of the shell's acceleration just after it is released?

    x= -13.5 (because it is the same as when it went up but just negative)
    v= 5.40

    I got -.2 by putting in -5.40=2a(-13.5)...but that is not the right answer obviously...

    Re: acceleration

    You may want to add units behind the numbers.

    actually what i just realized is that I should probably plug in

    -13.5=5.40+.5*a*.....okay never mind

    13.5m
    5.40 m/s
