When the displacement in the first second is 1 m, the instantaneous velocity at the end of the first second is () A. 1m/sB. 0.5m/sC. 2m/sD. 4m/s

When the displacement in the first second is 1 m, the instantaneous velocity at the end of the first second is () A. 1m/sB. 0.5m/sC. 2m/sD. 4m/s

Solution 1: a = 2m / S2, so v = at = 2 × 1 = 2m / s, so abd is wrong, and C is correct. Solution 2: the displacement of the object is x =. Vt & nbsp; & nbsp; & nbsp; ① the initial velocity is zero, and the average velocity of linear motion is. V = 0 + vt2 & nbsp; & nbsp; and ② VT = 2m / s, so abd is wrong, and C is correct
