The problem describes an Atwood machine setup from a previous stimulus (which I used for the first question).

Step 1: Identify the given values and the goal.
The problem describes an Atwood machine setup from a previous stimulus (which I used for the first question).

• Mass 1: $m_1 = 100 \text{ kg}$
• Mass 2: $m_2 = 50 \text{ kg}$
• Initial height of both masses from the ground: $h_0 = 30 \text{ m}$
• The system is released from rest.
• Acceleration due to gravity: $g = 9.8 \text{ m/s}^2$.

The question asks for the height ($h$) from the ground at which the kinetic energy ($KE_2$) of the 50 kg object ($m_2
