- A Cord Is Used To Vertically Lower An Initially Stationary Block Of Mass M 2 4 Kg At A Constant Downward Acceleration 1 (54.79 KiB) Viewed 28 times
A cord is used to vertically lower an initially stationary block of mass M = 2.4 kg at a constant downward acceleration of g/8. When the block has fallen a distance d = 2.7 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 i (b) Number i (c) Number i (d) Number i Units Units Units Units
