Physics 13 Online
OpenStudy (anonymous):

A hallway display of energy is constructed in which several people pull on a rope that lifts a block 1.00 m. The display indicates that 1.00 J of work is done. What is the mass of the block? Unless otherwise directed, assume that air resistance is negligible. Draw energy bar graphs to solve the problem.

OpenStudy (gollywolly):

J= force X distance, force=kg X acceleration.
