A series of two 2.0 kg blocks are attached together through string B.Two of the blocks weigh each 2.0 kg and are now being use for a new experiment. The blocks are being pulled upwards by another string A with a force of 25 N.
What is the acceleration of the blocks?(3.55 m/s^2[Down])
What is the tension in the string connecting the two blocks? Solve using the FBD of the block connected by string A and B (12.5 N)

  1. As each block has 2 kg mass so overall we have 4 kg mass. And overall weight of the body is 39. 2 N. So the net force must be 14. 2 N down,39. 2 - 25... a=F/m so a=14. 2/4 =3. 55N
