Respuesta :
The magnitude of the force exerted by the girl on the woman is 100 N .
How is it calculated?
Given,
m₁ = 80 Kg
m₂ = 30 Kg
F1 = 100 N
F₂ = ?
By applying Newton's third law of motion, the force exerted by the girl is equal in magnitude to the force exerted by the boy but in opposite direction.
F₁ = F₂
F₁ = m₁ × a₁
F₂ = m₂ × a₂
∴ 100 = 80 × a₁
∴ a₁ = 100 / 80
∴ a₁ = 1.25 m/s
we know,
m₁ × a₁ = m₂ × a₂
∴ 80 × 1.25 = 30 × a₂
∴ 100 = 30 × a₂
∴ a₂ = 100 / 30
∴ a₂ = 3.33 m/s
Therefore,
F₂ = m₂ × a₂
∴ F₂ = 30 × 3.33
∴ F₂ = 100 N
Hence, the magnitude of the force exerted by the girl on the woman is 100 N .
What is magnitude of force?
- A force magnitude is a number that expresses the
- A force magnitude is a number that expresses the strength of a force.
- Example: Suppose the force is = 10 N towards the east. "East" represents the direction, and "10" represents the strength of the force.
- A quantity is therefore basically a "value" or "amount" of a physical quantity it is always a scalar quantity.
