Question

A particle moves along a number line such that its position s at any time t, t(greaterthan or equal to), is given by s(t)=2t^3-15t^2+24t+1.

A) Find the average velocity over the time interval [1,2].

B) Find the instantaneous velocity at t=2

C) When is the particle at rest?




It has been a while since we have been on this topic and i have forgotten how to set any of these up. Any help would be wonderful =)
