An object is 10 mters long and has a weight of 125N. The weight of the object is determined by the expression, 250N= a10m+B kg/m. What are the units of a and B

Newton is kg-m/s²

Since both sides of the equal sign must have the same units, we conclude:

a * m = kg-m/s²
and
B *kg/m = kg-m/s²

Find the units of a and B by solving the two given equations.
