Understand the stimulus and the question.

Step 1: Understand the stimulus and the question.
The stimulus describes an Atwood machine setup:

• 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.

Question (গ) asks: "If the 50 kg object in the stimulus is released, at what height from the ground will its kinetic energy be one-third of its potential energy?"
The phrase "গতিশক্তি উদ্দীপকের এক-তৃতীয়াংশ হবে?" (kinetic energy will be one-third of the stimulus's [something])
