rad s⁻¹
rev
= diameter of the merry-go-round = 5.1 m 
= radius of the merry-go-round = 
= 
= 2.55 m 
= time period of the merry-go-round = 4.1 s 
= initial angular velocity of merry-go-round 
= final angular velocity of merry-go-round = 0 rad s⁻¹
= time taken to stop = 25 s
= angular displacement = ?
= Number of revolutions made before stopping
rad

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
