To determine which object will have the least acceleration when the same force is applied to each, we can use Newton's second law of motion, which states that \( F = ma \), where \( F \) is the force, \( m \) is the mass, and \( a \) is the acceleration. Rearranging this gives us \( a = \frac{F}{m} \).
Since the same force \( F \) is applied to each object, the acceleration is inversely proportional to the mass of the object. This means that the object with the greatest mass will have the least acceleration.
Based on the masses provided in the table:
- Textbook: 1.65 kg
- Hardcover novel: 0.88 kg
- Paperback novel: 0.51 kg
- Spiral notebook: 0.54 kg
The textbook has the greatest mass (1.65 kg). Therefore, it will have the least acceleration.
The correct response is:
