Problem: A gun fires a bullet vertically into a 1.40-kg block of wood at rest on a thin horizontal sheet.
Part A: If the bullet has a mass of 26.8g and a speed of 230m/s, how high will the block rise into the air after the bullet becomes embedded in it?
I need help to find how high will the block rise into the air after the bullet becomes embedded in it and express your answer to three significant figures and include the appropriate units.
