Answer:
Fx  = 4.92 [N]
Fy = 0.868 [N]
Explanation:
Let's take the 10 degrees as a measure from the horizontal component to the vector.
Thus taking the components in the X & y axes respectively:
Fx = 5*cos(10) = 4.92 [N]
Fy = 5*sin(10) = 0.868 [N]
 
        
             
        
        
        
Answer:
D.   Satin Cloth
Explanation:
i thought it said glass, not grass lol
satin it the smoothest surface and therefore the least amount of friction.
