Question 1

This question is a long free-response question. Show your work for each part of the question.

The figure presents a diagram of three blocks, labeled 1 through 3. In the diagram, block 1 is resting on the floor. Block 2, which is smaller than block 1, is resting on top of block 1. Block 3, which is approximately the same size as block 1, is resting on a table. The right side of block 3 is attached to one end of a string which runs over a pulley located at the right edge of the table. The other end of the string is attached to the top of block 2.

Block 1 is resting on the floor with block 2 at rest on top of it. Block 3, at rest on a smooth table with negligible friction, is attached to block 2 by a string that passes over a pulley, as shown above. The string and pulley have negligible mass.

(a)

i. On the dot that represents block 1, draw and label the forces (not components) exerted on block 1. Each force must be represented by a distinct arrow starting on, and pointing away from, the dot. Draw the relative lengths of all arrows to reflect the relative magnitudes of the forces.
