When an object moves in a straight line with a uniform acceleration of 2m / s and the displacement in the second second is 12M, the initial velocity of the object is

A = 2m / S ^ 2, T2 = 1s (the second second), S2 = 12M, the displacement in the second second second is equal to the displacement in the first two seconds minus the displacement in the first second. Suppose the initial velocity is V0, then S2 = S2 = s2-s1 = [V0 * T2 + (a * T2 / 2)] - [V0 * T1 + (a * T1 ^ 2 / 2)], that is, 12 = [V0 * 2 + (2 * T2 / 2)]
