Question:

A motorcyclist who is moving along an x axis directed toward the east has an acceleration given by a - (6.1 – 1.2t) m/s2 for 0 < t < 6.0 s. At t = 0, the velocity and position of the cyclist arc 2.7 m/s and 7.3 m.
(a) What is the maximum speed achieved by the cyclist?
(b) What total distance does the cyclist travel between t = 0 and 6.0s?
