Explanation
Since the toy car is moving with a constant velocity, its acceleration is zero. According to Newton's second law of motion (F = ma), if the acceleration is zero, the net force acting on the object must also be zero, regardless of its mass.
Solution Steps
Step 1: Identify that the toy car is moving with a constant velocity of 0.5 m s⁻¹, which means its acceleration (a) is 0 m s⁻².
Step 2: Apply Newton's second law of motion, F = ma.
Step 3: Substitute the values into the equation: F = 100 g × 0 m s⁻² = 0 N.
