The acceleration is A1 and the motion time is T1. Then the acceleration is A2 and the motion is decelerated The acceleration is A1. The motion time is T1. Then the acceleration is A2. After T2, the velocity is exactly zero. Then the average velocity of the object in the whole process can be expressed as?

The acceleration is A1 and the motion time is T1. Then the acceleration is A2 and the motion is decelerated The acceleration is A1. The motion time is T1. Then the acceleration is A2. After T2, the velocity is exactly zero. Then the average velocity of the object in the whole process can be expressed as?

The average velocity of the whole process is equal to the total displacement s divided by the total time t
During acceleration, the displacement is S1 = 1 / 2 * A1 * T1 ^ 2
During deceleration, the displacement is S2 = 1 / 2 * A2 * T2 ^ 2
In addition, A1 * T1 = A2 * T2,
The average velocity is v = (S1 + S2) / (T1 + T2),
We can get v = 1 / 2 * A1 * T1 = 1 / 2 * A2 * T2
