a. what is their angular velocity in revolution per minute? degrees per minute? radians per minute?
b. what is the linear velocity?

Okay, you know that it is going 2 pi radians for every 20 seconds.
2 pi divided by 20=
pi divided by 10
That is the angular speed.
pi divided by 10 radians per second.
Now we know that the seat is 25 feet from center, and that this must be radius.
Multiply by 2 pi.
Whatever that number is, divided by 20, is the linear speed per second.
lol i just did this earlier this year....are you in precalc?
but yeah sorry i don't exactly remember how to do it haha
