Question:

A particle moves in a straight line so that the displacement, s metres, from a fixed-point O, is given by s = 2t³ – 17t² + 40t - 2, where t is the time is seconds after passing a point X on the line.

a. Find the distance OX.

b. Find the value of t when particle is first at rest.

c. Find the values of t for which the velocity is positive.

d. Find the values of t for which the velocity is negative.
