A cord is used to vertically lower an initially stationary block of mass M kg at a constant downward acceleration of g/4. The block has fallen a distance d. (Use any variable or symbol stated above as necessary.)
1. Discover the work done by the cord's force on the block.
WF =
2. Discover the work done by the weight of the block.
Wg =
3. Discover the kinetic energy of the block.
K =
4. Discover the speed of the block.
