question 42

Multiple Choice

• B)Both coefficients of friction must be less than 0.25.
• C)Both coefficients of friction must be greater than 0.25.
• D)The coefficient of static friction must be less than the coefficient of kinetic friction.
• E)The coefficient of static friction is greater than 0.25 while the coefficient of kinetic friction is less than 0.25.
