Consider the system composed of three blocks attached by massless strings over frictionless pulleys. Block C descends with constant velocity. The surface in contact with Block A is frictionless and the inclined plane where Block B is in contact with is rough. Draw the Free Body Diagram (FBD) of blocks A, B and C. C A 36.9 2. Two forces and act on a 5.00-kg object. Taking F-20.0 N and F 15.0 N, find the accelerations in (a) and (b) of the given figure below BUF L A LAI 3. Fill in the blanks. Imagine that you are holding a book weighing 4 N at rest on the palm of your hand Complete the following sentences: a. A downward force of magnitude 4 N is exerted on the book by the b. An upward force of magnitude is exerted on by your hand c. is the upward force in part (b) the reaction to the downward force in part (a)? d. The reaction to the force in part (a) is a force of magnitude Its direction is exerted on by e. The reaction to the force in part (b) is a force of magnitude exerted on by Its direction is The forces in parts (a) and (b) are equal and opposite because of Newton's
