The ceiling fan in the Engineering Building at the University of the Philippines (UP) Diliman spun lazily, doing little to cut the humid afternoon heat. But for Miguel, the temperature in the room was the least of his worries.

Epilogue: Key Takeaways for the Reader

Problems often ask for the total distance traveled, which requires identifying points where the particle reverses direction ( Deceleration and Position:

Segments:
0→1: ( |6-2| = 4 , \textm )
1→3: ( |2-6| = 4 , \textm )
3→4: ( |6-2| = 4 , \textm )
Total = ( 4+4+4 = 12 , \textm )

  • If $v > 0$ and $a > 0$: Speeding up.
  • If $v > 0$ and $a < 0$: Slowing down.
  • If $v < 0$ and $a < 0$: Speeding up (moving backward faster).

The Problem: A particle moves along a straight line. At time t = 0, it is at the origin. Its velocity is given by the function v(t) = 3t² – 12t + 9. Determine: (a) The time when the particle returns to the origin. (b) The total distance traveled during the time interval t = 0 to t = 4 seconds.
