an automobile starts from rest and accelerates to a final velocity in 2 stages along a straight road. each stage occupies the same amount of time. In stage 1, the magnitude of the car's acceleration is 3.0m/s^2. the magnitude of the car's velocity at the end of stage 2 is 2.5 times greater than it is at the end of stage 1. find the magnitude of the acceleration in stage 2.
