A 2500 kg car rounds a flat curve of radius 75 m at speed of 80 km/h.
a) will the car make the turn or will it skid off the rouad if the pavement is dry and the force of static friction from the tires is 14000 n ? prove it.
b) if the pavement is icy and the force of static friction is 6000 n, what is the maximum speed the car could safely go around the curve?
