Question
The function s(t) describes the position of a particle moving along
a coordinate line, where s is in feet and t is in seconds.
s(t) = t3 – 12t, t > 0
-
(a) Find the velocity and acceleration functions.
v(t) =
a(t)
(b) Find the position, velocity, speed, and acceleration at time t = 4.
s(4) =
ft
v(4) =
ft/s
Speed
ft/s
a(4)
ft/s?
(c) At what times is the particle stopped?
Number of times the particle stopped: Choose one▼

(d) When is the particle speeding up? Slowing down?
Speeding up:
Choose onev
Slowing down: Choose onev
(e) Find the total distance traveled by the particle
from time t = 0 to time t = 10.
The total distance =
ft
