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. (a) Calculate the thrust exerted by the rope as it lands on the scale. (b) At the instant when the amount of rope at rest on the scale has a weight of 2.5 N, does the scale read 2.5 N, more than 2.5 N, or less than 2.5 N? Explain. (c) Check y oui’ answer to part (b) by calculating the reading on the scale at this time.
