Final answer:
Using Newton's second law of motion, the net force acting on a 10 kg shopping cart accelerating at 1 m/s² is calculated as 10 N.
Step-by-step explanation:
To determine the net force acting on a 10 kg shopping cart that accelerates at 1 m/s², one can use Newton's second law of motion. The law states that the net force on an object is equal to the mass of the object multiplied by its acceleration (F = m * a).
In this case, with a mass of 10 kg and an acceleration of 1 m/s², the net force can be calculated as follows:
F = m * a
F = 10 kg * 1 m/s²
F = 10 N
Therefore, the correct answer is b) 10 N.
