A block of mass 5kg is lifted 2 meters in 3 seconds. Compute the work done in joules and in ergs.© BrainMass Inc. brainmass.com December 24, 2021, 4:59 pm ad1c9bdddf
The force required to lift the block (at constant velocity) is equal in magnitude ( and opposite in direction) to the weight of the block.
The work done in joules is computed. The magnitudes are found.
