A horizontal force of 750 N is needed to overcome the force of static friction between a level floor and a 250-kg crate.If g = 9.8 m/s²,what is the coefficient of static friction? A)3.0 B)0.15 C)0.28 D)0.31

Question

Quizplus · Accepted Answer

The coefficient of static friction (μ) is calculated using the formula: μ = F / (m * g), where F is the force of static friction, m is the mass, and g is the acceleration due to gravity. Substituting the given values: μ = 750 N / (250 kg * 9.8 m/s²) = 0.31.
