A cord is used to vertically lower an initially stationary


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.

v =
