The position of a particle moving on a horizontal line (where s is in meters to the right of a fixed reference point and t in seconds after the start of the observation) is s = (1/3)+3 - 6t2 + 36t + 5. (a) Find the velocity and acceleration as functions of t. Velocity, in meters per second, at time t : Acceleration, in meters per second, per second, at time t : (b) Find the acceleration after 1 second. Acceleration, in meters per second, per second, after 1 second : (c) Find the acceleration at the instant when the velocity is 0. Acceleration, in meters per second, per second : 0
