1. The problem statement, all variables and given/known data A light string is wrapped around the outer rim of a solid uniform cylinder of diameter 75.0 cm that can rotate without friction about an axle through its center. A 3.00 kg stone is tied to the free end of the string, as shown in the figure . When the system is released from rest, you determine that the stone reaches a speed of 3.50 m/s after having fallen 2.50 m. What is the mass of the cylinder? 2. Relevant equations KE=1/2(1/2MR^2)ω^2 v=rω 3. The attempt at a solution v=rw 3.50=.375w w=9.3 ke=1/2(1/2M(.375)^2)(9.3)^2 I am doing this right and is 30406kg correct?
