A1500 kg sedan goes through a wide intersection traveling from north to south when it is hit by a 2100 kg suv traveling from east to west. the two cars become enmeshed due to the impact and slide as one thereafter. on-the-scene measurements show that the coefficient of kinetic friction between the tires of these cars and the pavement is 0.750, and the cars slide to a halt at a point 5.39 m west and 6.37 m south of the impact point. how fast was sedan traveling just before the collision? how fast was suv traveling just before the collision?
