# Fridge Force Comparison#

Ahmed pushes a refrigerator (with force $$\vec{F}_{yr}$$) at a constant 1 $$\rm{m/s}$$ across a level rough floor. A second identical refrigerator is pushed (with force $$\vec{F}_{fr}$$) across the same floor by their friend at a constant 2 $$\rm{m/s}$$.

## Part 1#

Compare the magnitudes of the forces involved while the refrigerators are moving at these speeds.

• $$F_{yr} = 2F_{fr}$$

• $$F_{yr} = \dfrac{1}{2} F_{fr}$$

• $$F_{yr} = F_{fr} \neq 0$$

• $$F_{yr} = 0, F_{fr} = 0$$

• Since $$f_{s} \leq \mu_{s}n$$, it is impossible to tell
