Question
A 4-kg block is connected by means of a massless rope to a 2-kg block that is hanging over the edge of a table. The rope is threaded through a pulley that extends out over the edge of the table. Complete the following statement: If the 4-kg block is to begin sliding, the coefficient of static friction between the 4-kg block and the surface must be (don't forget about the inertia of both blocks):
a. greater than 0.5, but less than 1.
b. less than 0.5, but greater than zero.
c. greater than 2.
d. less than zero.
e. greater than 1, but less than 2.
Explanation / Answer
b. less than 0.5, but greater than zero.
