(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 27-g rifle bullet traveling 230m/s buries itself in a 3.3-kg pendulum hanging on a 2.9-m-long string, which makes the pendulum swing upward in an arc.

Determine the vertical and horizontal components of the pendulum's maximum displacement.

x=? and h=?

2. Relevant equations

v= (m+M)/m * sqr root (2gh)

3. The attempt at a solution

I just expanded on the above equation and derived several others ..dont know where to go next.. L = length of string ; M=block's mass ; h=max height ; x=distance on x axis ; m=bullet's mass

v= (m+M)/m * sqr root (2gh)

(v* (m/m+M)^2)/(2g)=h

h= L(1-cos theta)

cos-1 theta(-1 ((h/L)-1) = theta

L sin theta = x

EDIT: sorry nicksauce. I have now included the question.
