113. The position of a particle moving along the x-axis varies with time according tox(t) = 5.012 – 4.01³ m. Find (a) the velocity and-acceleration of the particle as functions

of time,(b) the velocity and acceleration at t = 2.0 s, (c)the time at which the position is a maximum, (d)the time at which the velocity is zero, and (e) the maximum position.
