A record of travel along a straight path is as follows:

1. Start from rest with constant acceleration of 2.40 m/s2 for 14.0 s.

2. Maintain a constant velocity for the next 2.85 min.

3. Apply a constant negative acceleration of −8.39 m/s2 for 4.00 s.

(a) What was the total displacement for the trip?

_______m

(b) What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?

leg 1. ________ m/s

leg 2. ________ m/s

leg 3. ________ m/s

complete trip ________ m/s

I really need help with this question. I keep getting it wrong and im struggling with it.
