If a curve with a radius of 94 m is properly banked for a car traveling 68 km/h on frictionless embankment, what must be the coefficient of static friction for a car not to skid when traveling at 83 km/h ?
If a curve with a radius of 90 m is properly banked for a car traveling 68 km/h, what must be the coefficient of static friction for a car not to skid when traveling at 96 km/h?
If a curve with a radius of 89 m is properly banked for a car traveling 73 km/h , what must be the coefficient of static friction for a car not to skid when traveling at 89 km/h ?
If a curve with a radius of 88 m is properly banked for a car traveling 68 km/h , what must be the coefficient of static friction for a car not to skid when traveling at 91 km/h ? Express your answer using two significant figures.
This question is typical on some driver’s li- cense exams: A car moving at 47 km/h skids 12 m with locked brakes. How far will the car skid with locked brakes at 94 km/h? Assume that energy loss is due only to sliding friction. Answer in units of m.

If a car generates 16 hp when traveling at a steady 100 km/h , what must be the average force exerted on the car due to friction and air resistance? Express your answer to two significant figures and include the appropriate units.
Car A is traveling eastward at 85 km/h. Car B is traveling westward with a speed of 65 km/h. According to classical relativity, the velocity of car B as measured by the driver of car A would be According to classical relativity, the velocity of car B as measured by the driver of car A would be 20 km/h eastward. 150 km/h westward. 20 km/h westward. 150 km/h eastward.
A car is traveling at a steady 87 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 7.2 m/s2 . How far is the motorcycle from the car when it reaches this speed?
A 1428 kg car traveling at 73.0 km/h hits a second 1170 kg car traveling at 42.0 km/h in the same direction. If the first car is traveling at 57.5 km/h after the collision, what is the speed of the second car (in km/h) after the collision?
