A road safety problem. A corner in a flat road has a constant radius of r = 25 \text{ m}r=25 m. Air resistance and rolling resistance are zero. (Hey, I want a car like that!), and the car is travelling at constant speed. What is the maximum speed our car can go round this corner without skidding? For a reasonably clean, dry road, take the coefficients of static and kinetic friction to be \mu_{s} = 1.0μs=1.0 and \mu_{k} = 0.80μk=0.80....

A car of mass M= 1300 kg
traveling at 65.0 km/hour enters a banked turn covered with ice.
The road is banked at an angle , and there is no friction between the road and
the car's tires. (Intro 1 figure) . Use g= 9.80 m/s^2 throughout
this problem.
What is the radius (in meters) of the turn if =
20.0 (assuming the car continues in
uniform circular motion around the turn)?

A flat (unbanked) curve on a highway has a radius of 240 m . A car successfully rounds the curve at a speed of 37 m/s but is on the verge of skidding out. Part A If the coefficient of static friction between the car’s tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve? Express your answer in meters per second to two significant figures. part B...
