SUMMARY
The acceleration of the smaller mass in a two-mass pulley system, consisting of masses 1.98 kg and 2.68 kg, is calculated using Newton's second law. The total mass of the system is 4.66 kg, resulting in a net force of 45.668 N when multiplied by the acceleration due to gravity (9.8 m/s²). Dividing this net force by the smaller mass (1.98 kg) yields an acceleration of 23.1 m/s². This calculation confirms that the approach to solving for acceleration using the unbalanced external force is correct.
