Answer:
60.18 N
Explanation:
Given that:
The force applied on the sled = 100 N
Suppose, the angle between the sled rope and the ground = 53°
The horizontal force which acts in the horizontal direction can be expressed as:



But if the angle between the sled rope is parallel to the ground. Then, we use an angle on a straight line which is = 180°


= 100 × -1
= -100 N
