A 34.4 kg child is sitting in the middle of a 198.3 kg merry-go-round of radius 2.23 m while it is spinning at a rate of 4.7 rpm. If the child moves out to the edge, how fast will it be spinning? (Hint: use conservation of angular momentum)
rpm
A 0.31 kg ball is stuck on a disk spinning at 5.55 rad/s. If its angular momentum is 0.1548 J*s, how far is it from the center?
m
A 28 kg child is sitting on the edge of a 103.5 kg merry-go-round of radius 2.41 m while it is spinning at a rate of 1.687 rpm. If the child moves to the center, how fast will it be spinning? (Hint: use conservation of angular momentum)
A 0.306 kg ball is stuck on a disk spinning at 49 rpm. If its angular momentum is 1.538 J*s, how far is it from the center?
A 37.2 kg child is sitting in the middle of a 172 kg merry-go-round of radius 2.7 m while it is spinning at a rate of 2.3 rpm. If the child moves out to the edge, how fast will it be spinning? (Hint: use conservation of angular momentum)
A 33.6 kg child is sitting in the middle of a 133.4 kg merry-go-round of radius 2.46 m while it is spinning at a rate of 3.5 rpm. If the child moves out to the edge, how fast will it be spinning? (Hint: use conservation of angular momentum)
