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.

Respuesta :

Answer:

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

1) The ratio of the masses is; m₁/m₂ = 2

2) The piece that has the larger mass is; The piece with the smaller kinetic energy has the larger mass.

What is the ratio of the mases?

We are told that an object breaks into two as a result of an explosion. Now, since One piece has twice the kinetic energy of the other piece, it means that;

K₁ = 2K₂

Thus;

¹/₂m₁v² = 2(¹/₂m₂v²)

v² and ¹/₂ will cancel out to give us;

m₁ = 2m₂

Thus; m₁/m₂ = 2

b) Since one piece has twice the kinetic energy of another piece, then it means that the piece with the smaller kinetic energy will have the larger mass.
