Asked by Tony

d. Now you pull your sister across the floor so that she moves with increasing speed (accelerates). Compare the magnitude of the force exerted by you on your sister, with the magnitude of the force she exerts on you. Are they the same or different? If they are not the same, which is larger? Why or why not?

are they the same (newtons third law)

or do you exert a force on your sister (since she accelerates)?
Answered by drwls
Newton's third law applies, regardless of who accelerates more. Perhaps one of you accelerates more than the other, or is restrained by other forces. It doesn't matter. Bodies apply equal and opposite forces upon one another.
