1. The problem statement, all variables and given/known data The pulley in system drawn below has radius 8.0 cm and mass 0.6 kg. The surface on which the 4.0 kg mass is resting is frictionless. Suppose the 2.0 kg block is released from rest. http://bcs.whfreeman.com/WebPub/Physics/tiplerphysics6e_bridge/question_bank_images/9-72.png?9954 1. What is the speed of the block in m/s after it falls a distance of 2.5 m. Round your answer to one decimal place. Derive a complete formula for the answer before substituting values to avoid round-off errors. Use g = 9.81 m/s^2. 2. What is the angular speed of the pulley in rad/s at the instant the block reaches a distance of 2.5 m? Round your answer to one decimal place. Derive a complete formula for the answer before substituting values to avoid round-off errors. Use g = 9.81 m/s^2. Round your answer to two significant figures. 2. Relevant equations 3. The attempt at a solution What I did is: T1=m1a (T1 is tension connecting the 4 kg block, m1 is the mass of 4 kg block) (T2-T1) = I [tex]\alpha[/tex] ( T2 is tension connecting the 2 kg block, I is the moment of inertia of pulley) m2g - T2 = m2a (m2 is mass of 2 kg block) These are the three equations I was able to find but how do I get the answers to these question?
