Suppose that the equation of motion for a particle (where [math] is in meters and [math] in seconds) is [math].
(a) Find the velocity and acceleration as functions of [math].

Velocity at time [math] =

Acceleration at time [math] =
(b) Find the acceleration after 1 second.

Acceleration after 1 second:
(c) Find the acceleration (in absolute value) at the instant when the velocity is 0.
