If minutes is unit of time and 10 meter per sec square is unit of acceleration and 100kg is unit of mass the new unit of work in joule is

Choosing three base units fixes all derived units. If the unit of mass is 100 kg, the unit of time a minute and the unit of acceleration a decameter per second squared, then the unit of energy (mass times acceleration) is kg decameter per second squared.

Note that under this choice of units length (acceleration times duration squared) would be measured in decameter per second squared times minute squared. This length unit equals 10 decameter times 60 squared, or 3600 km.
