Question

Two hockey players, Aaron and Brunnhilde, are pushing two pucks on a frictionless ice rink. The pucks are at first at rest on starting line. Brunnhilde is pushing puck B that has a mass three times as great as that of puck A, which Aaron is pushing. The players exert identical constant forces of magnitude F on their pucks, directed horizontally, towards finish line. They start pushing at the same time, and each player pushes his or her puck until it crosses the finish line, a distance d away.

Let pA be magnitude of the momentum of puck A at the instant it reaches the finish line. Likewise, pB is magnitude of the momentum of puck B at (possibly different) instant it reaches finish line. Which of following statements is correct?
Choose best selection.

a. pA=pB

b. pA<pB

c. pA>pB

d. You need more information to decide.
