Homework Statement
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=?
Homework Equations
v= (m+M)/m * sqr root (2gh)
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.
