You do 152 J of work on your sister while pulling her back on a swing, whose chain 4.7 m long. You start with the swing hanging vertically and pull it until the chain makes an angle of 26° with the vertical while your sister is at rest. What is your sister's mass, assuming negligible friction? m = kg
