A record of travel along a straight path is as follows:
1. Start from rest with constant acceleration of 2.65 m/s2 for 18.0 s.
2. Maintain a constant velocity for the next 1.40 min.
3. Apply a constant negative acceleration of -9.24 m/s2 for 5.16 s.
(a) What was the total displacement for the trip?
(b) What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?
| leg 1 |
