    Figure given shows the distance–time graph of the motion of a car. It follows from the graph that the car is

    Since x equals 1.2 t to the power of 2 end exponent which is in form x equals fraction numerator 1 over denominator 2 end fraction a t to the power of 2 end exponent
    Thus, the motion is uniformly accelerated
