Homework Statement
A bullet of mass m_{1} with initial horizontal speed v_{0} hits a wooden block of mass m_{2} initially at rest on an incline of angle β and embeds itself into the wooden block, how far up the incline will the bullet and block travel?
Homework Equations
[itex]\bar{P}_{initial}[/itex] = [itex]\bar{P}_{final}[/itex]
U = ΔT+Δ[itex]V_{g}[/itex]+Δ[itex]V_{e}[/itex]
The Attempt at a Solution
[itex]\bar{P}_{initial}[/itex] = m_{1}*v_{1}*[itex]\bar{e}_{i}[/itex]
[itex]\bar{P}_{final}[/itex] = (m_{1}+m_{2})v_{2}*(cos(β)[itex]\bar{e}_{i}[/itex]+sin(β)*[itex]\bar{e}_{j}[/itex])
v_{2}*sin(β) = 0 v_{2}*cos(β) = m_{1}*v_{1}/(m_{1}+m_{2}) ?
