. The two blocks in the figure below are attached to each other by a massless string that is wrapped
around a frictionless pulley.
YA
A. To the left
P
2.0 kg
4.0 kg
When the bottom 4.00-kg block is pulled to the left by the constant force P, the top 2.00-kg block
slides across it to the right. If the blocks move at a constant speed, then answer the following
questions.
(a) In which direction does the force of kinetic friction act on the 2.0 kg block from the 4.0 kg block?
B. To the right
OC. There is no friction between the 2.0kg block and the 4.0 kg block
Transcribed Image Text:. The two blocks in the figure below are attached to each other by a massless string that is wrapped around a frictionless pulley. YA A.

To the right OC. There is no friction between the 2.0kg block and the 4.0 kg block
(b) Two surfaces are in contact with the 4.0 kg block, the 2.0 kg block and the floor. In
what directions do the two friction forces act on the 4.0 kg block?
A. Both act to the left
B. Both act to the right
C. The force between the two blocks acts to the left and the force between the 4.0 kg block and
the floor acts to the right
D. The force between the two blocks acts to the right and the force between the 4.0 kg block and
the floor acts to the left
(c) Using this question, draw a free body diagram for each for each of the blocks in your notebook.
! No, that's only partially correct
