Here are some questions, i have helped many of you and i will give 20 points for helping me :) doing all the questions would be preferred have a great day

The position of a particle is given by s=t^3-6t^2+9^t, where s is in meters and t is in seconds.

A) Compute the velocity and acceleration of the particle at time t.

B) At what time is the velocity 0?

C) What is the total distance traveled by the particle on 0 less than/equal to t less than/equal to 4.
