how would you calculate the effect of acceleration on the precentage of useful work done?

sumF=ma,

W=FdcosT

W=dmacosT, substituting.

for some arbitrary acceleration, the work done is given by the equation.. If you want to use percentages, divide this number by the necessary work to achieve an optimal result, and multiply by 100. This method will however lead to some level of uncertainty constrained by the assumption that some optimal amount of work is the minimum amount of work needed in a system.

But what if the pillar doesn't move. Then won't there be zero work done again friction?
