It must be adopted in a short time, thank you) an object moves in a straight line with uniform acceleration, the initial velocity is 10m / s, and the acceleration is 2m / s When an object moves in a straight line with uniform acceleration, the initial velocity is 10m / s, and the acceleration is 2m / S ^ 2. What is the average velocity of the object in the second second second

V end = V beginning + at
So the velocity at the end of one second is 10 + 2x1 = 12m / s
At the end of the second second, the velocity is 10 + 2x2 = 14m / s
Average velocity = (12 + 14) / 2 = 13m / S
