Question

Let  s(t)=2t^3- 21t^2 +72t in meters be the position of a particle moving on the coordinate line after t seconds on the interval [0, 6].

a. Find the instantaneous velocity at t = 2 seconds.

b. Find the acceleration at t = 5 seconds.

c.When is the particle moving in a positive direction?

d. When is the particle moving in a negative direction?

e. When is the particle at rest?

Does s(0)-s(0) represent the total distance traveled from t = 0 to t = 6 seconds? Why or Why not?
