a particle moves aling a straight line and its position at time t is given by s(t)= (t^3)-13.5t^2+54t where s is measured in feet and t is seconds. consider t in the interval [0,infinity)

1) when is the particle moving in the positive direction? ( i tried (0,3) U(6, infinity) but it didnt work)

2) what is the total distance the particle travels travels between time 0 and time 7

3) when is the particle speeding up?

4) when is the particle slowing down?
