Physics

To find the acceleration of the box, we need to analyze the forces acting on it. The key forces are the tension in the rope and the component of the weight acting down the incline.

 

Step 1: Identify the forces

1. Weight of the box ():

 

2. Component of the weight acting parallel to the incline ():

 

3. Component of the weight acting perpendicular to the incline ():

 

4. Tension in the rope ():

The tension is 150 N, and we need to find its components:

Parallel to the incline ():
