- A Cord Is Used To Vertically Lower An Initially Stationary Block Of Mass M 4 6 Kg At A Constant Downward Acceleration Of 1 (34.82 KiB) Viewed 42 times
A cord is used to vertically lower an initially stationary block of mass M-4.6 kg at a constant downward acceleration of g/3. When the block has fallen a distance d-2.4 m, 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. (Note: Take the downward direction positive) (a) Number (b) Number (c) Number (d) Number Units Units Units Units J
