As Tony the fisherman reels in a "big one", he turns the spool on his fishing reel at the rate of 3.0 complete revolutions every second.?
A: If the radius of the reel is 3.5 cm , what is the linear speed of the fishing line as it is reeled in?
B:How would your answer to part A change if the radius of the reel were doubled?

c = 2πr
3.0 rev/sec (2πr/1rev) = 3(2pi*3.5cm)/1s
= 65.9734 cm/s, rounds to 66. cm/s
If radius doubled, linear speed is proportional and doubled.
