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

1. Start from rest with constant acceleration of 2.00 m/s2 for 13.0 s.
2. Maintain a constant velocity for the next 1.70 min.
3. Apply a constant negative acceleration of ?9.10 m/s2 for 2.86 s.

A car starts from a state of rest and drives along a level, straight road. For the first 30 s, the car speeds up with a constant acceleration of 2.50 m/s 2 , after which it continues at the constant velocity that it has acquired for the next 5.00 minutes, at which time the brakes are applied, and there is an acceleration of -2.2 m/s 2 until the car stops. What is the total displacement of the car from its...
