Two masses of 3.40 kg and 5.50 kg are connected by a light string that passes over a frictionless pulley. Determine the tension in the string.
Calculate the acceleration of m.
Calculate the distance each mass will move in the first 1.52 seconds of motion if they start from rest

You have given two masses. Which is m? Actually both will have the same acceleration.
Find the acceleration of each mass and equate them. Then solve for T. From that find the acceleration.
Chuck 86 said:so then the second equation would be m2g-T=-m2a?
Tension is a pulling force that is created when an object is connected to another object by a string, rope, or cable.
To calculate tension in a system with two masses connected by string, you can use Newton's second law, which states that the total force on an object is equal to its mass multiplied by its acceleration. In this case, you would calculate the acceleration of each mass separately and then use that value to solve for the tension in the string.
The tension in a string is directly proportional to the acceleration of the masses connected by the string. This means that as the tension increases, the acceleration also increases, and vice versa.
Yes, the angle of the string does affect the tension in the system. As the angle of the string increases, the tension in the string also increases. This is because a larger angle results in a greater vertical component of the tension force, which adds to the overall tension in the string.
The motion of two masses connected by string can be affected by the tension in the string, the masses of the objects, the angle of the string, and any external forces acting on the system. Friction and air resistance may also play a role in the motion of the masses.
