A record of travel along a straight path is as follows:
(a) Start from rest with constant acceleration of 3.51 m/s2 for 17.8 s;
(b) Constant velocity of 62.478 m/s for the next 0.946 min;
(c) Constant negative acceleration of
−10.9 m/s2 for 3.89 s.
What was the total displacement x for the
complete trip?
