Answer
To find the component of the weight acting down the slope, we use the formula:
Fdown=mgimesextsin(heta)
This component acts parallel to the surface of the slope.
Step 2
Component of weight acting normal to the slope

Answer
To find the component of the weight acting normal (perpendicular) to the slope, we use the formula:
Fnormal=mgimesextcos(heta)
This force acts perpendicular to the surface of the slope.
