WebAssign homework is ready.

Your WebAssign homework for Monday is ready.

In addition, the diagram above and the following queries* are something to consider as you study:

  1. Two blocks, of masses M = 3 kg and m = 2 kg, are in contact on a horizontal table.
  2. A constant horizontal force of magnitude F = 5 N is applied to block M as shown.
  3. There is a constant frictional force of magnitude f = 1 N between the table and the block m, but
  4. no frictional force between the table and the first block M.
That being the case, can you calculate the acceleration of the two blocks? Can you calculate the force of contact between the blocks?

Inquiring minds want to know!
