Example 9.13 Analyzing a Car Crash At a stoplight, a large truck (3000 kg) collides with a motionless small car (1200 kg). The truck comes to an instantaneous stop; the car slides straight ahead, coming to a stop after sliding 10 meters. The measured coefficient of friction between the car's tires and the road was 0.62. How fast was the truck moving at the moment of impact?

Analyzing a Car Crash
At a stoplight, a large truck (3000 kg) collides with a motionless small car (1200 kg). The truck comes to
an instantaneous stop; the car slides straight ahead, coming to a stop after sliding 10 meters. The measured
coefficient of friction between the car's tires and the road was 0.62. How fast was the truck moving at the moment
of impact?
Example 9.14
Traffic Collision
A small car of mass 1200 kg traveling east at 60 km/hr collides at an intersection with a truck of mass 3000 kg
that is traveling due north at 40 km/hr (Figure 9.23). The two vehicles are locked together. What is the velocity
of the combined wreckage?
