2(theres no symbols for pie...........what do i do)
ok
2pie radians=1 revolution
so figure out how many 2pies are there in the velocity and that will give you the answer
i.ans
15/2pie revolutions per second

What is the definition of a radian?
How many radians are there in one revolution? (Pi will come into this)
Once you've found this number you can just divide the 15 radians per second to get the revolutions per second.

1 radian = 180/pi.

There are 2 pi radians in one complete revolution
so 15 rad/s is approx 15/6.28 rev/s
i.e approx 2.4 rev/sec
