**Problem Description:**1. An object of mass \( m_1 = 5.60 \, \text{kg} \) is placed on a frictionless, horizontal table. It is connected to a string that passes over a pulley and is attached to a hanging object of mass \( m_2 = 9.50 \, \text{kg} \), as shown in the figure. Determine the speed of the masses after \( m_2 \) falls 1 meter. Use the principle of conservation of energy to solve this problem.**Diagram Explanation:**- The diagram illustrates a classic pulley setup: - \( m_1 \) is on the table and is connected to a string that goes over a pulley. - \( m_2 \) hangs vertically from the string.- The string and pulley system allows \( m_2 \) to descend, which will in turn pull \( m_1 \) horizontally across the table. **Key Concepts:**- **Conservation of Energy:** The total mechanical energy (potential + kinetic) in the system remains constant, assuming no friction or air resistance. - **Potential Energy:** Initially, only the hanging mass \( m_2 \) has potential energy due to its elevation.- **Kinetic Energy:** As \( m_2 \) falls, potential energy is converted into kinetic energy of both masses.

Consider a mass m, traveling initially at speed v, on which a constant net force F is applied in the same direction as its motion over a distance d.
