Physics

To find the stretch in the spring when a 5 kg block is pulled at an angle of 37° with an acceleration of 2 m/s², we can follow these steps:

Given:

Mass of the block () = 5 kg

Spring constant () = 250 N/m

Acceleration () = 2 m/s²

Angle with the horizontal = 37°

 

Step 1: Calculate the net force required for acceleration

Using Newton's second law:

 

Step 2: Resolve the spring force

The force exerted by the spring has horizontal and vertical components. We need to find the horizontal component as it relates to the net force.

 

1. Horizontal component of the spring force ():
