Two Equal Masses Are Raised at Constant Velocity by Ropes

question 18

Multiple Choice

Two equal masses are raised at constant velocity by ropes that run over pulleys, as shown below. Mass B is raised twice as fast as mass A. The magnitudes of the forces are F_A and F_B, while the power supplied is respectively P_A and P_B. Which statement is correct?

• A) F_B = F_A; P_B = P_A.
• B) F_B = F_A; P_B = 2 P_A.
• C) F_B = 2 F_A; P_B = P_A.
• D) F_B = 2 F_A; P_B = 2 P_A.
• E) P_A = F_A; P_B = F_B.
