7. ### A wheel rotates at a constant rate of 85 rev/min. What is its angular speed?  rad/s What is the magnitude of its angular acceleration?  ?

We want radians/ sec 85 rev/min * 2πrad/rev * 1min/60s = 170π/60 rad/s = ω = 8.9 rad/s  Angular acceleration α = 0 (constant rate of 85rev/min means α = 0)

9. ### 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.?

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.
