1. An automobile starts from rest and accelerates to a final velocity in two 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.
2. I'm having some trouble, because it seems like there is missing info. Do I just use the velocities?
3. ((2.5)(3.0m/s^2))-3.0 m/s^2 = 7.5m/s^2 - 3.0m/s^2 = 4.5 m/s^2
