Sorry for the second post, but I want to know how to solve such problem when it comes to this situation. 1. The problem statement, all variables and given/known data A vertical rope is used to lower a block of mass M = 48.3 kg at a constant acceleration of magnitude a = 1.54 m/s2. Find WT, the work done by the tension in the cord if the mass moves down distance s = 2.47 m. 2. Relevant equations →W = mad 3. The attempt at a solution Hm... Tried to use this form: W = m(g - a)d But I'm not sure if I'm at the right path.
