ReWritten if you have trouble seeing image clearly: As Tony the fisherman reels

Question

ReWritten if you have trouble seeing image clearly:

As Tony the fisherman reels in a "big one" he turns the spool on his fishing reel at a constant rate of 3.0 revolutions every second.

(a) When the outer radius of the fishing line on the spool is 3.0 cm, what is the linear speed of the fishing line as it is reeled in?
________ cm/s

(b) Later on, when enough string has accumulated on the spool so that its outer radius is now 6 cm, re-evaluate part a.
_______ cm/s

(c) Suppose we split the total distance the fish must travel to the boat into two equal halves. Assuming Tony maintains this constant rotation rate, which half of the trip will takemore time?
---Select--- 1. the first half (from the catch point to the halfway point) 2. the second half (from the halfway point to the boat) 3. N/A - they will take the same time

Explanation / Answer

w = 3rev/s = 18.85 rad/s

part a )

v = r*w

v = 56.55 cm/s

part b)

v = wr

v = 113.1 cm/s

part c )

maintaing constant angular velocity

but d = v*t

v depands on r

so if r is less so linear velocity wil be less

the second half (from the halfway point to the boat)
