    Have posted the full question and solution. For part ii) shouldn't the tension in the wire no longer be 1488N since the acceleration has changed? Many thanks

    Well no because the force acting opposite to the direction of the object's motion has changed (resistance has increased). Acceleration is directly proportional to the force applied (if the mass of the objects are the same, where k = 1/m), so a greater resistance force means a smaller net upwards force, and therefore a smaller acceleration.

    The tension in the wire hasn't changed because the force applied to the load hasn't changed. The acceleration has changed because the net force is lower due to the forces resisting the motion of the object, but the total force remains unchanged.
