Question

Find out the acceleration and Tension in the wire for the below
set of masses and string.

Answer 1

Answer:

Now suppose I want to find the acceleration of the cart after it is let go. The string that attaches the two carts does two things. First, the string makes the magnitude of the acceleration for both carts is the same. Second, the magnitude of the tension on cart 1 and cart 2 has the same value (since it's the same string). This means I can draw the following two force diagrams for the two masses.
