When an object is moving in a straight line with uniform acceleration, the displacement in the first second is 6m, and the displacement in the second second is 10m

When an object is moving in a straight line with uniform acceleration, the displacement in the first second is 6m, and the displacement in the second second is 10m

The displacement in the first second is X1 = 6m, and the displacement in the second is x2 = 10m. From x2-x1 = at2, a = x2 − x1t2 = 10 − 612m / S2 = 4m / S2. From X1 = v0t + 12at2, V0 = x1t-12at = 61 − 12 × 4 × 1 (M / s) = 4m / s. A: the initial velocity of the object is 4m / s, and the acceleration is 4m / S2
