Question

A record of travel along a straight path is as follows: 1. Start from rest with constant acceleration of 2.60 m/s² for 14.0 s. 2. Maintain a constant velocity for the next 1.40 min. 3. Apply a constant negative acceleration of -9.40 m/s² for 3.87 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
