A fish takes the bait and pulls on the line with a force of 2.7 N. The fishing reel, which rotates without friction, is a cylinder of radius 0.048 m and mass 0.76 kg.

(a) What is the angular acceleration of the fishing reel?
? rad/s2
(b) How much line does the fish pull from the reel in 0.36 s?
? m

please help me start this...

Find the moment of Inertial for a cylinder of rad, and mass given.

Torque=I*angluaracceleration
and of course torque is force*radius.

b) angular displacement=1/2 angularacc*tim^2

and of course, line pulled in is equal to angular displacement*radius
