Question
Holding a long rope by its upper end, you lower it onto a scale. The rope has a mass of 0.160 kg per meter of length, and is lowered onto the scale at the constant rate of 1.30 m/s.
(1) Calculate thrust.
(2) At the instant when the amount of rope at rest on the scale has a weight of 2.74 N , does the scale read 2.74 N, more than 2.74 N, or less than 2.74 N?
Not sure how to set this problem up.
