Final answer:
The acceleration of a 58 kg box when a 203 N force is applied to it is calculated using Newton's second law to be 3.5 m/s².
Step-by-step explanation:
To find the acceleration of the box, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the force exerted on the box is 203 N and the mass of the box is 58 kg. So, using the formula F = ma, we can rearrange it to solve for acceleration: a = F/m = 203 N / 58 kg = 3.5 m/s². Therefore, the acceleration of the box will be 3.5 m/s². This means that for every kilogram of mass, the box experiences an acceleration of 3.5 meters per second squared.
