    296 N

    Explanation:

    Draw a free body diagram. The box has two forces on it: tension up and weight down.

    Apply Newton's second law:

    ∑F = ma

    T - mg = ma

    T = m (g + a)

    Given m = 196 N / 9.8 m/s² = 20 kg, and a = + 5 m/s²:

    T = (20 kg) (9.8 m/s² + 5 m/s²)

    T = 296 N
