To calculate the force applied to an object, you can use Newton's second law of motion, which states:

\[ F = m \cdot a \]

Where:

  • \( F \) is the force applied (in Newtons, N),
  • \( m \) is the mass (in kilograms, kg),
  • \( a \) is the acceleration (in meters per second squared, m/s²).

Let's calculate the force for each case:

  1. For the mass of 11 kg and acceleration of 4.863 m/s²: \[ F = 11 , \text{kg} \cdot 4.863 , \text{m/s}^2 = 53.493 , \text{N} \approx 53.5 , \text{N} \]

  2. For the mass of 7.5 kg and acceleration of 7.133 m/s²: \[ F = 7.5 , \text{kg} \cdot 7.133 , \text{m/s}^2 = 53.4975 , \text{N} \approx 53.5 , \text{N} \]

  3. For the mass of 17.1 kg and acceleration of 3.129 m/s²: \[ F = 17.1 , \text{kg} \cdot 3.129 , \text{m/s}^2 = 53.4669 , \text{N} \approx 53.5 , \text{N} \]

So, we have the forces calculated as follows:

  • For 11 kg and 4.863 m/s²: 53.5 N
  • For 7.5 kg and 7.133 m/s²: 53.5 N
  • For 17.1 kg and 3.129 m/s²: 53.5 N

The only value that matches from the options you provided based on mass and respective acceleration is 53.5 N.
