a.) kinetic energy from the mallet is transferred first to the orange ball and then to the purple ball.
b.) Mechanical waves transfer energy from the mallet through the air directly to the purple ball.
c.) kinetic energy from the mallet is transferred into potential energy first in the orange ball and then in the purple ball.
d.) Electromagnetic waves transfer energy from the mallet directly to the purple ball through the orange ball.
