To determine which object will have the least acceleration when the same force is applied to each, you can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
Where:
- \( F \) is the force applied,
- \( m \) is the mass of the object, and
- \( a \) is the acceleration.
Rearranging this formula to solve for acceleration, we get:
\[ a = \frac{F}{m} \]
Since the same force \( F \) is applied to all objects, the acceleration \( a \) is inversely proportional to mass \( m \). This means that the object with the highest mass will experience the least acceleration.
From the table, the masses are as follows:
- Textbook: 1.65 kg
- Hardcover novel: 0.88 kg
- Paperback novel: 0.51 kg
- Spiral notebook: 0.54 kg
The object with the highest mass is the textbook at 1.65 kg. Therefore, it will have the least acceleration when the same force is applied to all objects.
So the correct response is:
