A heavy box is pulled across the floor with a rope. The rope makes an angle of 60 degrees with the floor. A force of 75 N is exerted on the rope. What is the component of the force parallel to the floor

37.5 N

Explanation:

Horizontal component is represented by Fx and  is given as

Fx = F cos θ

Here,

θ = 60 degrees

F= 75 N

So,

Fx= 75 cos (60°)

==> Fx = 75 ×  0.5 =37.5 N

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
