A:Hi,
S = Vo*t + 0.5 * a * t^2
Mike: O.25t + 0.5 * 3 * t^2
John: 1t + 0.5 * 4.2 * t^2
We have to add 4 meters so that the distances will be equal:
4 + O.25t + 0.5 * 0.3 * t^2 = 1t + 0.5 * 4.2 * t^2
4 + 0.25t + 0.15t^2 = 1t + 2.1t^2
1.95t^2 + O.75t -4 = 0
195t^2 + 75t - 400 = 0
37t^2 + 15t - 80 = 0
Sorry have to leave now: get the t and from here get the distance.
Best regards,
