A chain of metal links with total mass 4kg is coiled up in a tight ball on a low-friction table. You pull on a link at one end of the chain with a constant force 70N. Eventually, the chain straightens out to its full length 2.5m, and you keep pulling until you have pulled your end of the chain a total distance 5.9m. m F . Consider the point particle system. What is the speed of the chain at this instant? v = Submit Answer Incorrect. Tries 2/5 Previous Tries Consider the real system. What is the total change in energy of the chain? Etot = Submit Answer | Tries 0/5 In straightening out, the links of the chain bang against each other, and their temperature rises. Assume that the process is so fast that there is insufficient time for significant thermal transfer of energy from the chain to the table, and ignore the small amount of energy radiated away as sound produced in the collisions among the links. Calculate the increase in thermal energy of the chain. Etherm = Submit Answer | Tries 0/5
