5... which is wrong?If the plane starts from the rest, its initial speed is zero,......

what is the speed after 10 seconds? I know the speed formula is S= distance/time but if i do that then my answer is 0.5... which is wrong? after 10 seconds of speeding 5m/s/s it should be 50m/s

a = (v2 - v1) / t

If the plane starts from the rest, its initial speed is zero, so

a = v2/t or v2 = a * t = 5 * 10 = 50 m/s
