Also, I the program used a matrix to solve the forces, what would the matrix calculation formula be?

But, that looks like an equilateral triangle, why is there different calculations?

Yes, the numbers on the members in the diagram.

How did it come up with those calculations though?

I don't have anything because I don't know how to calculate the forces.

Erm, let's just say a 100 metre bridge with trusses with an angle of 60 degress. The bridge weights 20 000 N.

How will I calculate the forces involved in a truss and suspension bridge, my teacher did not explain this fully and I'm confused as hell.

Could someone please help me with this?

No. Which do I use and how?

No. My teacher is a chem teacher teaching physics.

An item is thrown upwards with a vertical velocity of 50 m/s, what is it's greatest height and how long is it in the air for. I have no clue how to do that.

What about the first part of the question? I tried to average out the velocity and then using the d=vt formula I got 198m.

Is displacement the same as distance?

A body starts from rest with an acceleration of 11m/s². What is it's velocity after 6 seconds. (I got 66 for that) and how far did it travel? What formula do I have to use for this?

But, why are they different?
