PROBLEM 13.CQ2 Page 842 m Two small balls A and B with masses 2m and m respectively are released from rest at a heighth 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. (e) 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.
