Final answer:
When a net force of 45.8N is applied to a 9.3kg object, the acceleration is approximately 4.94m/s². When the net force is applied to an 11.23kg object, the acceleration is approximately 4.08m/s². If the force is doubled, the acceleration of both objects will double, resulting in an acceleration of approximately 8.16m/s².
Step-by-step explanation:
To determine the accelerations resulting from a net force, we can use the equation F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
For the first object with a mass of 9.3 kg and a net force of 45.8 N, we can use the equation a = F/m = 45.8 N / 9.3 kg = 4.94 m/s².
For the second object with a mass of 11.23 kg and the same net force of 45.8 N, we can again use the equation a = F/m = 45.8 N / 11.23 kg = 4.08 m/s².
If we double the force to 2 * 45.8 N = 91.6 N, the acceleration will also double for both objects. Therefore, the acceleration will become approximately 2 * 4.94 m/s² = 9.88 m/s² for the first object, and 2 * 4.08 m/s² = 8.16 m/s² for the second object.
Therefore, the correct answer is C. The acceleration will become approximately 8.16m/s².
