Concept

Problem: A student applies a 1.5 N horizontal force on a box of weight 20N on a floor. The static friction coefficient is 0.3. Does the box move? Explain your reasoning and SHOW WORK!

FREE Expert Solution

Frictional force:

f=μN

N = w

Static friction, fs, is equal to the applied force, Fapp, until Fapp > fs,max

The box will move if Fapp > fs,max
