QUESTIONO Suppose two people are pushing at different points on a meny-go-round How do we secount for their combined effectson the rotation of the merry-go -round? ANSWER We add the mugnitudes of their forces,calculate a total turque, and use Newtan's second law for rotation sum 7=16 We add the magnituder of their tomues and use Newion isecond law for notation, sum ^2=1pi We add the forces they each exert, calculate a total tomue, and use Newton's second law for rotation. 27 =16 Weade the torques crused by each person, accounting for direction, and use Newton's second law for rotation. sum F=15 IDONT KNOWYET
