The rotor of a "centrifuge" (originally at rest) is accelerated with an angular acceleration a for a time interval At, left at constant speed for a time interval Al, and then slowed down at a constant angular acceleration - until it stops rotating. What is the total angular displacement during this process

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Attach the free body diagram and i will you answer the question.! : d
