s = 4t^3 + 48t^2 + 180t
v = 12t^2 + 96t + 180 = 12(t^2+8t+15) -- ??? this seems strange
a = 12(2t+18) = 24(t+9)
Let s ( t ) = 4 t 3 + 48 t 2 + 180 t be the equation of motion for a particle. Find a function for the velocity.
v ( t ) =
Where does the velocity equal zero? [Hint: factor out the GCF.]
t= and t=
Find a function for the acceleration of the particle.
a(t)=
