Answer:
The force acting on the player's foot is, -50 N
Step-by-step explanation:
Given data,
The mass of the football, m = 0.5 kg
The soccer player kicks with a force of, F = 50 N
According to newton's III law of motion, Whenever a body exerts a force on an object, the object exerts the same magnitude of force on the body, but in the opposite direction.
According to the law,
F₁ = -F₂
Where
F₁ is the action force
F₂ is the reaction force
Hence, the force acting on the players's foot is F₂ = -50 N
