horizontal surface. The block is connected

by a cord passing over a pulley to another
block of mass 5.53 kg which hangs in the air,
as shown on the following picture. Assume
the cord to be light (massless and weightless)
and unstretchable and the pulley to have no
friction and no rotational inertia.

To help you understand this setup, let's break it down step by step:

1. The first block is placed on a horizontal surface. Let's call this block "Block 1."
2. Block 1 is connected to another block, which is hanging in the air. Let's call this block "Block 2."
3. The connection between the two blocks is made using a cord or rope that passes over a pulley.
4. The cord is assumed to be light, which means it has no mass or weight.
5. The cord is also assumed to be unstretchable, meaning it does not stretch when a force is applied to it.
6. The pulley is assumed to have no friction, which means there is no resistance to the motion of the cord as it passes over the pulley.
7. The pulley is also assumed to have no rotational inertia, which means it does not require any additional force to start or stop its rotation.
