A fast-moving superhero in a comic book runs around a circular, 70-m-diameter track five and a half times (ending up directly opposite her starting point) in 3.0s
My answer is 403 rad/s, but I think its incorrect. I think that for everyone 1 turn, it takes 0.54545454 seconds.
What is her angular speed, in rad/s? lol
There are 2 pi radians in a circle. five and a half circles = 11 pi radians. 11 pi radians in 3 seconds = 11/3 pi radians per second
You got the same answers as everyone else.
