A 1000-kg car is slowly picking up speed as it goes around a horizontal unbanked curve whose radius is 100 m. The coefficient of static friction between the tires and the road is 0.35. At what
Speed will the car begin to skid sideways?
A) 9.3 m/s
B) 19 m/s
C) 24 m/s
D) 35 m/s
E) 34 m/s

The maximum speed before skidding can be calculated using the formula v = sqrt(μ * g * r), where μ is the coefficient of static friction, g is the acceleration due to gravity (9.8 m/s²), and r is the radius of the curve. Substituting the given values, v = sqrt(0.35 * 9.8 * 100) = 18.5 m/s, which rounds to 19 m/s.
