A particle has velocity v=t2-4t+3 m,s-1 for 0

Question

A particle has velocity v=t2-4t+3 m,s-1 for 0 <= t 5 seconds. Find the open time intervals on which its speed is increasing and those on which it is decreasing. Justify your answer.

Accepted Answer

Speed increases on $(1,2)$ and $(3,5)$; decreases on $(0,1)$ and $(2,3)$, with time in seconds.

Speed intervals across rest and zero acceleration
