Step 1

Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

 

Given the position vs time graph:

Physics homework question answer, step 1, image 1

Here we have to find the velocity at t=6s and as the line is nearly straight between points (a,b) and (c,d).
