Tracy (of mass 49 kg) and Tom (of mass
65 kg) are standing at rest in the center of the
roller rink, facing each other, free to move.
Tracy pushes oﬀ Tom with her hands and remains in contact with Tom’s hands, applying
a constant force for 0.5 s. Tracy moves 0.35 m
during this time. When she stops pushing oﬀ
Tom, she moves at a constant speed.
What is Tracy’s constant acceleration
during her time of contact with Tom?
