An internal explosion breaks an object, initially at rest, into two pieces, one of which has 1.3 times the mass of the other. if 8800 j is released in the explosion, all of which goes into the kinetic energy of the two pieces, how much kinetic energy does each piece acquire?

k_2 =3826.08 J

K_1 = 4973.91 J

Explanation:

from conservation of momentum principle

we know that kinetic energy is given as

we have ,

therefore

now

k_2 =3826.08 J

K_1 = 4973.91 J

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
