Physics

To find the stretch in the spring due to the pulling force, we need to analyze the forces acting on the block.

 

Given:

Mass of the block () = 6 kg

Spring constant () = 100 N/m

Tension in the rope () = 40 N

Angle of the rope with the horizontal = 60°

 

Step 1: Resolve the tension into components

The tension can be resolved into horizontal and vertical components:

1. Horizontal component ():

 

2. Vertical component ():
