Holding a long rope by its upper end, you lower it onto a scale. The rope has a mass of 0.13 kg per meter of length, and is lowered onto the scale at the constant rate of 1.4 m/s. Calculate the thrust exerted by the rope as it lands on the scale.
At the instant when the amount of rope at rest on the scale has a weight of 2.5N, does the scale read 2.5N, more than 2.5N, or less than 2.5N?
