If the displacement of an object moving in a straight line with uniform velocity is s in time t, and the instantaneous velocity in the middle of the time is V1, and the instantaneous velocity in the middle of the displacement is V2, then () A. Whether it is uniform acceleration or uniform deceleration, V1 < V2b. Whether it is uniform acceleration or uniform deceleration, V1 > V2C. Whether it is uniform acceleration or uniform deceleration, V1 = v2d. When it is uniform acceleration, V1 < V2, when it is uniform deceleration, V1 > v2

If the displacement of an object moving in a straight line with uniform velocity is s in time t, and the instantaneous velocity in the middle of the time is V1, and the instantaneous velocity in the middle of the displacement is V2, then () A. Whether it is uniform acceleration or uniform deceleration, V1 < V2b. Whether it is uniform acceleration or uniform deceleration, V1 > V2C. Whether it is uniform acceleration or uniform deceleration, V1 = v2d. When it is uniform acceleration, V1 < V2, when it is uniform deceleration, V1 > v2

Let the initial velocity of the object be V0 and the final velocity be V, then according to the velocity time relationship, there is the instantaneous velocity V1 = V0 + at2 = 2v0 + at2 = V0 + (V0 + at) 2 = V0 + v2. According to the velocity displacement relationship, the instantaneous velocity V2 of the object at the middle displacement satisfies the following equation: V22 − V20 = 2as2 = V2 & nbsp; − V22
