Sketch or describe the FBD from for finding the static friction of the experiment. You can upload a picture or describe where all the vectors/forces point.
If describing, you can use phrases like: The weight is straight up The force is straight down The tension goes up the wooden block The force goes down the wooden block (Or anything else that would describe the FBD.)



Answer :

Frictional force μk =  T - ma / mg

As block is moving with acceleration 'a', so we will we equilibrium equation.

T - f = ma

T - μk N = ma

μk = T - ma/N

μk = T - ma / mg

where T = tension in rope

          m = mass of block of wood

          g = acceleration due to gravity

The net force acting on an object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original version. This law suggests that an object's acceleration is directly related to its mass if it has a constant mass.
