Student A and Student B are each standing on a skateboard. Student A pushes gently on Student B to start her moving. Student B starts moving away from Student A. What will happen to Student A and why?

• Student A will not move, because no forces are acting on her

• Student A will move toward Student B, because the same force affects both of them

• Student A will immediately stop moving because of friction

• Student A will move away from Student B, because an equal and opposite force pushes on her
