To determine which object will experience the greatest acceleration based on Newton's second law, we use the formula:
\[ \text{Acceleration} (a) = \frac{\text{Force} (F)}{\text{Mass} (m)} \]
This means that acceleration is directly proportional to the force applied and inversely proportional to the mass of the object.
To find the object that will experience the greatest acceleration, you should look for the object with the highest force relative to its mass, calculated using the formula above.
If you provide the specific forces and masses of the five objects from the chart mentioned, I can help you determine which object will experience the greatest acceleration.
