1. The problem statement, all variables and given/known data A cord is used to vertically lower an initially stationary block of mass M at a constant downward acceleration of g/4. When the block has fallen a distance d, find (a)the work done by the cord’s force on the block, (b) the work done by the gravitational force on the block, (c) the kinetic energy of the block, and (d) the speed of the block. [Maintain Significant Figures] 2. Relevant equations F=m*a W=F*d 3. The attempt at a solution I have no idea how to even begin this problem. First of all, I cannot even begin to comprehend how to obtain an answer consisting of actual numbers from a mass "M" and a distance "d". The only physical number I have is g/4 which is 2.45m/s^2. If someone can help me with this problem, it will be greatly appreciated.
