A 60cm diameter bike wheel starts at rest and develops an angular speed of 12.0 rad/s in 10 seconds. What linear distance does the bike travel?

Answer 1

Average speed* time
= (1/2)*(final speed)*time
= (1/2)*R*w*time
= (1/2)*(0.60 m)*12 rad/s*10 s
= 36 m

Answer 2

a clothes washer starts from rest and spins up with an angular accceleration of 10/rad/s^2. Determine the angle through which the washer has moved afer 6 seconds.
