question 56

Multiple Choice

Two masses, M_A and M_B, with M_B = 2M_A, are released at the same time and allowed to fall straight down. Neglect air resistance. When we compare their kinetic energies after they have fallen equal distances, we find that

• A) K_B = K_A.
• B) K_B = 2K_A.
• C) K_B = 4K_A.
• D) K_A = 2K_B.
• E) K_A = 4K_B.
