One car with a mass m1=1000kg
moving east had collided with a car of mass m2=1200kg
moving north. The two cars, stuck together, skid at an angle of 35°
north of east for a distance of 19m
. The coefficient of kinetic friction between the tires and the road is 0.75
. The speed limit for each car was 70km/h
. (a) Was the car with mass m1
speeding? (b) Was the car with mass m2
speeding?
