Two cars simultaneosly enter an intersection with 35 degrees between their headings. the car on the left weighs 5000 lbf and is going 45 mph the car on the right weighs 8000 lbf and is going 60 mph. If both drivers lock their brakes at the instant of collision until they stop after rebound how far apart are the cars when they come to rest. The friction coefficient between the tires and the road is uk=0.8 and the coefficent of restitution for the collision is er=0.4. If the duration of impact is 0.5 seconds what is the magnitude of the average loads on people in the cars during the impact.
