Round your answer to three decimal places. A car is traveling at 144 km/h due south at a point 4 5 kilometer north of an intersection. A police car is traveling at 128 km/h due west at a point 2 5 kilometer due east of the same intersection. At that instant, the radar in the police car measures the rate at which the distance between the two cars is changing. What does the radar gun register?

A 1600 kg sedan goes through a wide intersection traveling from north to south when it is hit by a 2200 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 5.60 m west and 6.10 m south of...
