Answer:
the horizontal component of the force is 50 N
Step-by-step explanation:
Given;
force applied by the man, F = 100 N
angle of inclination of the force, θ = 60⁰
mass of the dog, m = 20 kg
The horizontal component of the force is calculated as;
![F_x = F* cos(\theta)\\\\F_x = 100 \ N * cos(60^0)\\\\F_x = 100\ N * 0.5\\\\F_x = 50 \ N](https://img.qammunity.org/2022/formulas/physics/college/za4i31lcsev58285sx4u2q7u6g5yqnbfnx.png)
Therefore, the horizontal component of the force is 50 N
