Two children are throwing snowballs at each other atop a frozen lake with negligible friction. Both are initially at rest when one child throws a snowball (m1 m/s at the other child (m2 the child, it deforms and sticks to her jacket. The child, with 1.2 kg) with a speed of 7.3 31 kg). When the snowball hits the snowball crushed against her jacket, starts sliding across the ice as a result of the hit. What fraction of the snowball's mechanical energy was converted into heat/internal energy as it was being deformed?
