If the initial velocity V0 of an object is 2 m / s and the displacement it passes through in the third second is 4.5 m, then its acceleration is 0

If the initial velocity V0 of an object is 2 m / s and the displacement it passes through in the third second is 4.5 m, then its acceleration is 0

The velocity at the end of the second second is V2 = V0 + at2 = 2 + 2A
The velocity at the end of the third second is V3 = V0 + at3 = 2 + 3a
According to the average velocity formula: x = (V2 + V3) t / 2 = (4 + 5a) * 1 / 2 = 4.5
So a = 1m / S ^ 2
