Answer:
Option B. 0.5 N.
Explanation:
Data obtained from the question include:
Mass (m) = 1 Kg
Acceleration (a) = 0.5 m/s²
Force (F) =?
Force is defined as the product of mass (m) and acceleration (a). Mathematically, it is expressed as:
Force (F) = mass (m) × acceleration (a)
F = ma
Using the above equation, we can obtain the force exerted on the floor as follow:
Mass (m) = 1 Kg
Acceleration (a) = 0.5 m/s²
Force (F) =?
F = ma
F = 1 × 0.5
F = 0.5 N
Thus, the car exerted a force of 0.5 N on the floor.
