Calculate the parallel component of the weight of the object on the inclined plane below.
1 answer:
Answer:
4. Wx = 42.47[N]
Explanation:
In order to solve this problem, we must first make a free body diagram, of the forces acting on the body in the inclined plane.
As we can see in the attached image, the component of the weight parallel to the surface of the inclined plane can be obtained by the sine of the angle.

<h3>What is horizontal and vertical component?</h3>The horizontal velocity component () describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (
) describes the influence of the velocity in displacing the projectile vertically.
According to the question,
The women pulls the dog with a force of 30 N at an angle of 29° from the horizontal.
Horizontal component= 30cos(29°) = 22.2 N
Vertical component = 30sin(29°) = 19.8 N
Therefore,
The horizontal component would tend to make the dog move forward and the vertical component would tend lift it off the ground.
Hence,
19.8 N force is tending to lift Rover vertically off the ground.
