In a hypothetical engineering school the following set of base units is introduced:
Length L~=20cm, Mass M~=50g, Time T~=0.10s.
Using these base units, answer the questions below.
a. (a) Obtain the conversion factor between the school’s unit of force and the newton (SI).
b. (b) A certain machine designed in the school delivers a mechanical work of 250 "school force × school length". Convert this work into joule.
