The horizontal component of force is 5.47 lb
<u>Step-by-step explanation:</u>
Given that a boy pulls his sled with a rope.
The rope makes an angle with horizontal = 70 degree
If a pull on the rope is needed to move the sled = 16 pounds
We need to find the horizontal component of force
In given scenario, the force used in this scenario is a vector addition of the horizontal and the vertical force component. The horizontal force component is calculated by multiplying the applied force by the cosine of the angle of the applied force from the horizontal plane in which it is found: horizontal force component = applied force x cos 70 degree
Horizontal component force =
Here, given applied force, f = 16 pounds
Then, horizontal component of force =
Horizontal component of force = 16×0.342
Hence, horizontal component of force = 5.47 lb
