Examine the forces acting on a car on a ramp. select the forces or force components that need to be added together to calculate the net force in the x-direction. check all that apply. fn –ff –fg fg (cos 15°) fg (sin 15°)

The answer is -Ff & Fg(sin 15°)

Frictional force, and Weight,

Explanation:

The attached figure shows the free body diagram of a car placed at the ramp. The net forces acting the car :

1. Normal force

2. Weight, mg

3. Frictional force

But the forces acting on the car in x- direction or horizontal path are frictional force (which acts in opposite direction of the motion) and of its weight.

So, the correct options are :
