A= 0.5 m/s² and F= 2.5 N

Explanation:

Force = mass * acceleration

Since we still don't have the value for acceleration, let us calculate it using the formula:  Δx = vi (t) + 1/2 at²

Rearranging the formula we have:

a = [2Δx] / vi (t) + t²

a = [2 (1m)] / 0 (2s) + (2s)²

a = (2m) / 4s²

a = 1/2 or 0.5 m/s²

Force = 5kg * 1/2 m/s²

F = 2.5 N
