Two block are arranged at the end of a massless string. The system starts from rest. When the 4.01 kg mass fallen through 0.336m, its downward speed is 1.32 m/s. the acceleration gravity is 9.8 m/s^2. what is the frictional force between the 5.3 kg mass and the table?

  • General physics -

    It is unclear to me where the blocks are doing, and in what direction they are moving.

  • General physics -

    the 5.3 kg block is on the table and the 4.01 kg block is hanging
