A 1500-kg car rounds an unbanked curve with a radius of 52 m at a speed of 14 m/s.What minimum coefficient of friction must exist between the road and tires to prevent the car from slipping? (g = 9.8 m/s²) A) 0.18 B) 0.30 C) 0.28 D) 0.38

Question

Quizplus · Accepted Answer

The minimum coefficient of friction (μ) can be calculated using the formula for centripetal force: μ = v²/(rg). Substituting the given values: μ = (14 m/s)² / (52 m * 9.8 m/s²) = 0.38.
