An object is observed for a 5 second interval. During this time, the objects velocity increases from 2 m/s to a final velocity and the object travels 75 m. The acceleration of the object is constant. Given this information, which of the following statements is not correct?

a)The average velocity is 15 m/s.
b)The final velocity of the object is 26 m/s.
c)The acceleration of the object is 5.2 m/s^2

    avgvelocity*time=distance
    avgvelocity=75/5=15m/s

    avg velocity=initial velocity+1/2 finalvelocity
    15=2+1/2 finalvelocity
    vinal velocity=26m/s

    a=changevelocity/time=(26-2)/5=24/5 m/s
