An object initially at rest breaks into two pieces as the result of an explosion. one piece has twice the kinetic energy of the other piece.
part a
what is the ratio of the masses of the two pieces?

1. m1/m2= square root 2
2. m1/m2=2

which piece has the larger mass?
the piece with the larger kinetic energy has the larger mass.
the piece with the smaller kinetic energy has the larger mass.

a) m1/m2 = 2 is correct

b) the answer above is incorrect, the piece with the smaller kinetic energy has the largest mass

Explanation:

a) m1/m2 = 2 is correct

b) the answer above is incorrect, the piece with the smaller kinetic energy has the largest mass
