Remember
Fn = Weight = mg
on horizontal surface
Step-by-step explanation:
Ex) A 5.0 kg Steel block is resting on a *horizontal table*. The coefficient of static friction (us) is 0.75 and the uk is 0.57.
a) What minimum force is needed to start this block moving?
fs= Fnus = Fgus = mgus
fs = mgus
= 5.0 kg(9.8 m/s2)(.75)
= 37. N
