To solve the problem of calculating the work done in pulling the entire rope onto the table, we can follow these steps: ### Step 1: Understand the Problem We have a uniform rope of length 3 m and mass 1 kg. Out of this, 80 cm (or 0.8 m) of the rope is hanging off the edge of the table. We need to calculate the work done to pull the entire rope onto the table. ### Step 2: Determine the Mass of the Hanging Portion Since the rope is uniform, we can find the mass of the hanging portion of the rope. The mass per unit length (linear mass density) of the rope can be calculated as: ...
