The less massive person, presumably the daughter, has the greater final speed.

Work Step by Step

By Newton’s third law, each person feels the same magnitude of force. By Newton’s second law, F = ma, the acceleration is a = F/m. For equal net forces acting on the 2 people for the same time interval, the smaller-mass person will have the greater acceleration and thus the greater final speed.
