Physics

To find the normal force acting on a crate sliding down a frictionless inclined plane angled at 36°, we can follow these steps:

 

1. Calculate the weight of the crate:

where:

 

 

2. Resolve the weight into components:

The weight can be resolved into two components:

The component perpendicular to the incline (which contributes to the normal force):

 

The component parallel to the incline (which causes the object to slide down):
