The simplest winch consists of 2 members: a block 1 and a drum 2.
Given: the block 1 is ascending with the speed V1=2,5m/s. The drum 2 is a disk of radius R1=49cm.Find: algebraical angular velocity of drum 2 (in rad/s) (considering it positive if directed counterclockwise and negative if clockwise) ω2 = ?
