The car accelerates uniformly along a straight line from rest at the rate of 2.3 m/s^2.
If an object starts with an initial velocity of u and is being accelerated at a rate a m/s^2, the velocity of the object after time t is given by v where v = u + a*t. The velocity of the object after it has traveled a distance s is v where v^2 - u^2 = 2*a*s.
Here, the initial velocity of the car is 0 m/s and the rate of acceleration is 2.3 m/s^2. It is not possible to determine the final velocity as neither the total time for which the car travels nor the distance traveled is provided.

I thought it was a trick question maybe with T=1 since it was uniform acceleration. Not sure.
