A 2 gram bullet traveling at 1500 m/s [East] hits a 200 g block of wood at rest, and becomes embedded in it. If the block is suspended by long ropes, how high will it travel before it comes to rest?

calculate the velocity of the bullet/block combined mass with the conservation of momentum equation. Now, knowing the velocity, you can set

finalPotentailEnergy=initialKineticenergy

mgh=1/2 m v^2

and solve for height h.
