B. Investigating the relationship a system with constant mass. 1. Measure the mass of the trolley. 2. Ensure that the track is stable and secure. 3. Cut a length of string which extends from the trolley at its maximum height and for about 5 cm over the pulley. 4. Attach one end of the string to the trolley and the other end to the hook of the slotted mass holder. 5. Place four of the slotted mass pieces on the trolley. 6. Feed a new length of ticker tape through the ticker timer and attach it to the trolley. Label the tape with the mass of the slotted mass holder (and the mass pieces on it).

To investigate the relationship in a system with constant mass, we can follow the steps outlined in your procedure. Here’s a detailed breakdown of each step: ### Step 1: Measure the Mass of the Trolley - Use a digital scale to measure the mass of the trolley. Record this value as \( m_t \). ### Step 2: Ensure the Track is Stable and Secure - Check that the track is level and free from any obstructions. Ensure that it is securely mounted to prevent any movement during the experiment. ### Step 3: Cut a Length of String - Cut a piece of string that is long enough to extend from the trolley at its maximum height to about 5 cm over the pulley. This will allow for smooth movement without any slack. ### Step 4: Attach the String to the Trolley and Slotted Mass Holder - Attach one end of the string to the trolley. Make sure it is securely fastened. - Attach the other end of the string to the hook of the slotted mass holder. This will allow the mass to hang freely and create a force due to gravity. ### Step 5: Place Slotted Mass Pieces on the Trolley - Place four slotted mass pieces on the trolley. Record the total mass of the trolley and the slotted masses combined as \( m_{total} = m_t + m_s \), where \( m_s \) is the mass of the slotted masses. ### Step 6: Feed Ticker Tape Through the Ticker Timer - Feed a new length of ticker tape through the ticker timer. Ensure that it is properly aligned and can move freely. - Attach the end of the ticker tape to the trolley. This will record the motion of the trolley as it moves. ### Label the Tape - As the experiment progresses, label the ticker tape with the mass of the slotted mass holder and the mass pieces on it. This will help in analyzing the data later. ### Conclusion By following these steps, you will set up an experiment to investigate the relationship between the mass of the trolley and the forces acting on it. The ticker tape will provide data on the motion of the trolley, which can be analyzed to understand the dynamics of the system. If you need further calculations or analysis based on the data collected, please provide the specific values, and I can assist you with that!
