Question

A merry-go-round is rotating at the rate of 15 rev/min. Express this rotational velocity in rev/s?

Answer 1

To convert the merry-go-round's rotational velocity from 15 rev/min to rev/s, divide by 60, which gives a result of 0.25 rev/s.

Step-by-step explanation:

To convert the rotational velocity of the merry-go-round from revolutions per minute (rev/min) to revolutions per second (rev/s), you can use the following calculation:

Thus, the merry-go-round rotating at 15 rev/min would have a rotational velocity of:

15 rev/min ÷ 60 s/min = 0.25 rev/s

Therefore, the merry-go-round's rotational velocity is 0.25 rev/s.
