A bullet of mass 45 g is fired at a speed of 220 m/s into a 5.0 kg sandbag hanging from a string from the ceiling. The sandbag absorbs the bullet and begins to swing. To what maximum vertical height will it rise?
Answered by bobpursley
use conservation of momentum to find initial velocity for the sandbag. Then, calculate the KE that sandbag has. Set that to the PE it will gain, solve for height.

Is there no kinetic energy after Collison when the sand bag is swinging?
