An electric car starts from rest and accelerates for 20s at a rate of 2.0 m/s along a straight line. Then the vehicle slows at a constant rate of 1 m/s? until it stops. All of this motion takes place along a straight line. a) How far does the vehicle travel from start to stop? b) Please sketch the a-t, v-t, and s-t graphs to demonstrate the car motion?
