A 36 g rifle bullet traveling 310 m/s buries itself in a 5.2 kg pendulum hanging on a 2m long string, which makes the pendulum swing upward in an arc. Determine the maximum verticle displacement of the pendulum (height)(g=9.8m/s^2)

2. Relevant equations

Pi = Pf

Law of conservation

3. The attempt at a solution

well i solved it out and im pretty sure im right, i found the velocity to be 2.131 m/s then plugged it into the law of conservation equation where the masses cancel out and you end up with 1/2(2.131)^2 = gh

h = .2318

but my question is because it says the pendulum hangs on a 2m long string, how does that impact the problem, do i subtract this height from the string? or vice versa? or add it?. I mean i know a pendulum is like a string or rod or w/e with a weight attached but the way its worded is like that theres an extra 2m string or something? does that impact the MAXIMUM vertical displacement at all? i'm just a little confused, thank you if u can help!
