Sorry, I'm very rusty with this...
I have two equations:
T = za
and
T - mg = -ma
Somehow, they get "combined" and to solve for "a" it is:
a = (m / (z + m) ) * g
can someone please explain the process of how it got to this?
I figured out that we substitue for T in the second one to get:
za - mg = -ma
but I get really lost trying to solve for "a".
Please help!
b.t.w. sorry, I'm not a math or physics student, I'm trying to learn this stuff myself.
