To solve the problem of the 93 kg man lowering himself from a height of 10.0 m while connected to a 65 kg sandbag, we can follow these steps: ### Step 1: Identify the Forces - The weight of the man (W_m) is given by: \[ W_m = m_m \cdot g = 93 \, \text{kg} \cdot 9.81 \, \text{m/s}^2 = 913.53 \, \text{N} \] - The weight of the sandbag (W_s) is given by: ...
