The object moves in a straight line with uniform acceleration at an initial velocity of 2m / s, and the acceleration is 1m / s. calculate the average velocity within the first 6S and the first 8s of the velocity at the end of the third second

The velocity at the end of the third second is v = V0 + at = 2 + 1 * 3 = 5m / s
The average velocity in the first six seconds is s = v0t + 1 / 2at & # 178; = 30 V = s / T = 5m / s
The average velocity in the first 8 s is s = v0t + 1 / 2at & # 178; = 48 V = s / T = 6m / s
