A car moves at a velocity of 8.5 meters per second. It then accelerates at a constant rate of 2.5 m/s^2 for a total time of 5 seconds. How fast is the car moving at the end of the 5 seconds? I got 21 mps ... is this right?

2. Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constant current. (Use a numerical value for the constant.)
