The two blocks in an Atwood machine have masses 2.0 kg and 3.0 kg. Find the work done by gravity during the fourth second after the system is released from rest.

Explanation

To solve the problem of finding the work done by gravity during the fourth second after the system is released from rest in an Atwood machine with masses 2.0 kg and 3.0 kg, we can follow these steps:

### Step 1: Identify the masses and the gravitational force
We have two masses:
- \( m_1 = 2.0 \, \text{kg} \) (the lighter mass)
- \( m_2 = 3.0 \, \text{kg} \) (the heavier mass)

The gravitational force acting on each mass is given by:
