I'm having a hard time with understanding this

36. The two masses (M1 = 2.2kg, M2 = 3.2kg) are each initially 1.80m above the ground, and the massless frictionless pulley is 4.8m above the ground. What maximum height does the lighter object reach after the system is released? (Hint: First determine the acceleration of the lighter mass ad then its velocity at the moment the heavier one hits the ground. This is its launch speed.)
Newton's Laws of Motion are three physical laws that describe the relationship between an object's motion and the forces acting upon it. They were developed by Sir Isaac Newton in the late 17th century and are considered the foundation of classical mechanics.
The first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
The second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be mathematically represented as F = ma, where F is force, m is mass, and a is acceleration.
The third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.
Tension is a force that is transmitted through a string, rope, cable, or any other type of flexible connector. In the context of Newton's laws of motion, tension can be considered an external force acting on an object, and can affect an object's motion and acceleration.
