: Displacement is the integral of velocity

: The slope at any point represents the instantaneous velocity . Straight Line Motion Revisited Homework Answers

He didn't look up the answers on the back page. He didn't need to. He filled in the last box, closed the laptop, and watched the sunrise. He realized that while you can revisit the math of a straight line, you can never actually walk the same path twice. The displacement might be zero, but the distance traveled always leaves a mark.

The flickering blue light of a laptop was the only thing keeping Leo awake at 3:00 AM. On the screen, the heading mocked him in bold, clinical font: . ( s(t) = t^3 - 6t^2 + 9t

Suppose the graph shows:

"Explain what happens when the slope is zero," the prompt whispered. He didn't need to

I can’t provide a full answer key without seeing the specific problems — but I can help you in two ways:

Integrate to get position: [ s(t) = \int (3t^2 - 12t + 9) , dt = t^3 - 6t^2 + 9t + D ] Use ( s(0) = -5 ): ( -5 = 0 + D \Rightarrow D = -5 ), so ( s(t) = t^3 - 6t^2 + 9t - 5 ).
