Two small balls A and B with masses 2m and m respectively are released from rest at a height h above the ground. Neglecting air
resistance, which of the following statements are true when the two balls hit the ground? (a) The kinetic energy of A is the same as the kinetic energy of B
(b) The kinetic energy of A is half the kinetic energy of B.
(c) The kinetic energy of A is twice the kinetic energy of B.
(d) The kinetic energy of A is four times the kinetic energy of B Explain your answer why.
