An objectis at rest on an incline. The component of gravity acting downward and along the incline on the object is described as Fg,x = +8.0N. Which axis is pointing up the incline?
a. + x axis
b. + y axis
c. - x axis
d - y axis
The axis pointing up the incline is the positive y-axis (option b).
To determine which axis is pointing up the incline, we need to consider the direction of the component of gravity acting downward and along the incline. In this case, the component of gravity acting downward and along the incline is described as Fg,x = +8.0N.
The subscript "x" suggests that this component of gravity is measured in the x-direction. The positive sign in front of the value indicates that the force is acting in the positive x-direction.
Therefore, since the component of gravity is acting in the positive x-direction, we can conclude that the incline is positioned along the negative x-axis.
Hence, the answer is c. - x axis.
If Fg,x is pointing down positive then x is positive pointing down the slope
so
c ) -x axis
is up the incline
