Halliday, Resnick & Walker β Kinetic Energy and Work: Problem 21
21 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 cordβs 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.
π Solution Approach
Given: 21 A
Find: (a) the work done by the cordβs force on the block; (b) the work done by the gravitational force on the block; (c) the kinetic energy of the block
