Greetings!

I'm studying for my mechanics test in my school, and there is a specific exercise that none of my friends and coleagues know how to solve.

So I would like to ask for help, if someone could tell me how to approach this exercise at least. Or if there are any tutorials for exercises like this.

The image of the exercise is dropped below.

Thank you in advance!

has a dim'n been cut off at the bottom of the sketch ?

with that dim'n you should be able to determine the location of things, the angles of the links.
as I think the question is asking for the acceleration and velocity of the slider at this specific point,

Assuming you find the missing dimension, the lecture you didn't pay attention to was concerned with velocity diagrams, as a graphical method. Sadly it is may decades since I studied them. If we label the three pivots A B and C then it is obvious what the velocity of B is, and we know that C can only move horizontally, and must be 8 inches from B.

I have never done acceleration diagrams graphically, can't help you there.

Cheers
