Feng and isaac are riding on a merry-ground. feng rides on a horse at the outer rim of the circular platform, twice as far from the center of the circular platform as isaac, who rides on an inner horse. when the merry-go-round is rotating at a constant angular speed, what is feng’s angular speed?

The question is incomplete or missing details. here is the remaining part of the question ;

1. impossible to determine

2. half of Isaac’s

3. the same as Isaac’s

4. twice Isaac’s

The angular speed of feng will be the same as that of Isaac. Hence the answer is option 3

Explanation:

Since we have been told that both feng and isaac are riding on a merry go round i.e in a circular motion, irrespective of how fast one ride above the other, the angular speed will be constant since they are riding on a merry go round, as such both feng and isaac will maintain equal angular speed, hence the angular speed of feng will be the same as that of Isaac.
