Q. A race car starts from rest on a circular track of radius 455 m. The car's speed increases at the constant rate of 0.480 m/s2. At the point where the magnitudes of the centripetal and tangential accelerations are equal, find the following.(a) the speed of the race car

Q. A curve with a 125 m radius on a level road is banked at the correct angle for a speed of 20 {rm m/s}.If an automobile rounds this curve at 30 {rm m/s}, what is the minimum coefficient of static friction between tires and road needed to prevent skidding?
