A string is wound around a pulley. The free end of the string is attached to a metallic block. The pulley has a mass of 8.50 kg, a radius of 220 mm, and behaves like a uniform cylinder. You release the block from rest and notice that the block unwinds a 17.0 m length of the string in 6.50 s. What is the string's tension?
