Question

Sheldon is pulling a box of athletic equipment across the floor of the school gym. The box has a mass of 51.9 kg. As he pulls, the box accelerates at a rate of 0.355 m/s?. How much force is Sheldon exerting on the box? • 27.7 N • 18.4N • 93.0 N • 146 N

Answer 1

18.4 N

Note: This answer is based off the assumption that there is no friction that is opposing motion.

Step-by-step explanation:

To calculate the force exerted by Sheldon on the box, we can use Newton's second law of motion, which states that force is equal to mass times acceleration (F = ma).

Given:

• m = 51.9 kg
• a = 0.355 m/s²

Plug these forces into our formula and solve with a calculator:

⇒ F = (51.9 kg)(0.355 m/s²)

∴ F ≈ 18.4 N

Thus, Sheldon is exerting a force of approximately 18.4 Newtons on the box. ​​
