Understanding the Concepts

* Newton's Second Law: Force (F) is directly proportional to acceleration (a) and mass (m): F = ma.

* Combined Mass: When objects are glued together, their masses add up.

Applying the Concepts

1. Original Situation:

- Let the mass of each block be 'm'.

- Let the original force applied to a single block be 'F'.

- The acceleration of a single block would be a = F/m.

2. Glued Together:

- The combined mass of the two blocks is 2m.

- The force applied is doubled, so it's 2F.

3. Calculating Acceleration:

- Using Newton's Second Law: a = (2F) / (2m) = F/m

Conclusion

The acceleration of the two blocks glued together, when pulled with twice the original force, will be the same as the acceleration of a single block pulled with the original force.

Why?

The doubled force perfectly compensates for the doubled mass, resulting in the same acceleration.
