Question
Consider the situation depicted in this applet. The red block moves along a rough surface. The system begins at rest. You may assume that the pulley and rope are both massless and frictionless. Open the next applet. Now, you can see all of the forces. Note that the gravitational force acting on the red block is represented by wr? and that on the light grey block by wg?. Which of the following shows the relation between the magnitude of the tension |T? | acting on the light gray block and the magnitude of the tension |T??| acting on the red block? T? |=|T??|
|T? |=|T??+fk?|
|T? |=|T???fk?|
|T? |=|T??+wg?|
|T? |=|T???wg?|
Explanation / Answer
first one.T? |=|T??|
