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...

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
