A 7 kg mass is placed on a table with Ms= 0.18 and Mk= 0.15. How much mass must be suspended on m in order to start the 5 kg moving? What is the resulting acceleration? This is basically the situation we set up in Lab several times…... a pulley system is placed such that the weight of mass 2 will pull horizontally to the table the 7 kg is placed upon.
