5 A snowball sits at the top of the hill. Which of the following changes will increase the kinetic energy of the snowball? A Additional snow falls on the snowball, increasing its mass. B The snowball is pushed and rolls down the hill, gaining speed. The weather warms and the snowball melts, decreasing its mass. D The snowball is moved and now sits on a hill that is higher.
it is B because in order to have kinetic energy the object has to be in motion, because if it wasnt in motion and sitting on the hill then it has potentail energy, hope this helps
